The Govier book says they are 1970-1971 360 heads. Those heads were used on both the '70 AAR 'Cuda/T/A Challenger and had 2.02 valves, and on the '71 360, which had 1.88 valves. If the heads are factory 2.02 intakes, they are from the 340 Six Pack. If they have been enlarged at any time in their lives, they are from the '71 360. Either way, you have the best flowing production heads put on a small block Mopar. I happened into a set as well, and they aren't cheap. Do you happen to have the rocker arms? Those will tell you for certain, as they look like the adjustable 273 rockers, but have the rockers for the intake valves (I think) are angled. Another way to tell is that the pushrod holes are moved farther from the intake ports than on a standard 340. I hope this helps.

Offset rocker arms huh? Sounds like 340 parts to me. The 915's are 340-360 peices. Best flowing head? Well, when ya port them out, there tops. Out of the box, they may be a bit much for your 318. Valve size has the most impact here. 2.02's are large for 318's. Use of a Hyd. or Mech. cam requires the correct pushrod with the adjustable rockers.

If they're 340 Six Pack heads, they won't work on a 318 anyway. If the rockers look like those on the 318, and are original, they are from a 340+6. The 915 heads were used on the '70 T/A and the 1972 340/360, according to the Part and Casting Numbers Book 1962-1974, fifth printing, page 24.

No, they're not W2 heads. I have heard of folks using the W2 heads on earlier "LA" engines, but don't know what it entails. The heads you have are definitely the early 340/360 heads; we just have to determine which. The standard 340/360 heads used shaft mounted nonadjustable rockers, whereas the W2 uses the pedastal mounted adjustable type. They also have more rounded ports, whereas the older "LA" engines had more squared off ports. As I understand, the Magnum engines used the W2 heads as standard equipment

No stock engines used w2 heads. And the cast iron version w2 heads have cast in stock looking pedastals for the rocker shafts. Only the aluminum has the add on pedastals. The w2 head is a race head and wont work good on any street engine. It's for high rpm usage in the 6500 to 8700 range. Most dont run that high an rpm. These were desigend for oval track use not drag use.
What you have old ram is a stock set of 340 heads. And all 318 340 and 360 heads will fit and work on any small blocks. The heads you have will work great on a built street engine. Even your 318 if done right. |

Hear ye hear ye
MoPar only has cast iron W-2 heads. They come with and without cast in rocker stands. There was another company that did the W-2's in aluminum, but it doesn't matter now..
The W-2 head comes in various sized chambers. I do believe they come as small as 55 cc and top out at 72 cc area. The 340 T-A -6pak heads have the offset rockers like the W-2. Since the W-2 copied the stock style, they'll swap. The airflow curves of a W-2 in there stock and unported form aren't as radical as most think. They could be used on a 318 if done correctly. No need for getting crazy ethier. Pics are cool. Lay some on us. |

"340 TA Heads
Those are the 340 TA heads... I have an identical set on the shelf in the garage right now, with the same rocker set up.They were taken off a 1970 TA 340, which we used in one of the late model stock cars.It originally had a hydralic cam.
These are the forerunners of the W2 heads w/bolt on pedistals,W2 econo short valve & W2 long valve with cast in pedistals,then Aluminum W2, then Aluminum W5 as we know them to day. |

The intake pushrod holes are relocated the same as mine....and on mine the number cast into the offset intake rocker is "072"
You have got a good set of heads there. There is a very good book about Bob Mullen and his involvment in the development from these lowly casting into the "W" series heads.Mopar Performance byLarry Schreib & Larry Atherton. Isbn 0-931472-03-2 |

Yep, they look like 340 Six Pack heads to me... You doubters can admit your having been wrong at any time, rumblefish360, Mopardad, and dwc43. By the way, in How to Rebuild Small-Block Mopar Engines, Taylor and Hofer say specifically that the 340 T/A heads will not fit any other LA engine.

You want to make those heads really cool?...
Put them up for sale and someone will probably pay good $ for them which you can put into new heads more suited to your engine. Or maybe I'm just nuts, but it seems like anything of of a T/A brings in some good coin. |

Indeed they do bring in good money. The 340 Six Packs were officially only available in 1970, but the few remaining ones went out as four barrel 340s the following year. I originally wanted one for my '50 Coronet until I learned how very rare they have become over the years. I even had an intake for one of them a few years back, but financial troubles caused me to sell it. I agree with you; I'd put them on Ebay and watch the cash roll in. I'm guessing that since they look to be compete, they will bring in $500 or better as is.

well now dont forget... they can still always go on the charger and will eventually now since i see they wont work on my 318 , but i was thinkin the heads on our 73 charger 340 would directly bolt on my 318.... so that made me beleive that these would too.. so is it the pushrods that make these heads so different from others??
i have the pushrods too thanx guys |

The major differences of the 340+6 engines, other than the induction, were the fact that they had extra webbing in the block, four bolt mains, an adjustable valve train, and slightly relocated pushrod holes. As I said before, my literature says that they won't work on anything but a 340+6, and I assume that's because of the pushrod holes being relocated. I can't confirm or deny that since I've never seen a real 340+6 engine disassembled, but I think if I were you, I'd listen to the small block experts.

The only thing different in stock T/A / AAR heads compared to other '915' heads is the relocated pushrod holes. They have cast in rocker pedestals stock, and the casting is just the same as in any 360 '915' head. They are just ground for 2.02" intake valves. A lot of regular 340's also used 2.02" intake valves, but with regular valvetrain and pushrod location. They have nothing to do with W2 heads and the only thing different to regular 340 heads porting wise is that you can open the pushrod pinch wider. You can use them in a 318 with he correct pushrods and the rockers you have, but they are propably not worth anything power wise gainst any other 340/360 head. I would propably try to put them for sale in Ebay or something and see if I could get enough money out of them to buy new Edelbrocks instead.

Someone who wants/needs correct T/A AAR stuff will cream over them and spend what the $ on them!
Sell those bad boys! |

Man I say find a 340 block and put those suckers on it. Hell I think the 318 crank is the same size as the 340 aint it? Or do you need one of the special 340 T/A AAR blocks to run these heads?

Okay, so I was wrong about the four bolt mains. I can admit that, so no big deal. I knew right away that those were 340+6 heads, but since you want to be nit picky, trying to save face, I'll remind you that you said "They are plain old J heads." And since I wouldn't waste my time putting W2 heads on a 318, I have no idea how it would work. It's not a theory either, I am again going by the same book that I always have.

I can tell you from first hand knowledge that the X,J,TA, heads will work great on a 318. We've used them many times on dirt track cars where rules limited engine size or that's what someone wanted to try out. We've also used all above plus W2's on 360 race engines as well with great results, butthen again the W2 is a race only head.

Has anyone but me noticed that folks here have a hard time admitting that they're wrong?
