W2 360 Heads on a 340...good combo?
i haven't ever dealt w/360 motors, or interchanging parts.....
my 340 has W2 Race Modified 360 Heads on it (360 is stamped on the intake port of #2 under the valve cover) how well does this head work w/eddy's aluminum Troker II Highrise? also, is this a good head for NOS and racing applications? apparently it works great (not sure about NOS yet, not hooked up...) it runs like a champ, but what are your opinions?

?? really?
thats what a guy told me from P.A.W..... i ordered some roller rocker arms and thought i had stock but they wouldn't fit because the pushrod studs weren't off centered. we had to order the rocker arms for the W2 and W5 heads. I was told that they were Race Modified W2 heads for high performance 340's the only funny thing is that 360 was stamped on the inside. i'll look for more numbers and keep you posted

i have a set of W-2's on my car, i dont see where it says 360 on them either. what some people call the "race"version is the long valve heads. thats what i have. the others are econo's. if they say 360 on the heads then there probaly standard 360 heads. what are the cast numbers? have you had the intake off? w-2 heads have a oval intake port, standard heads have a rectangular
port. either set of heads can handle Nitrous if the rest of the motor is up to par

There are two styles of W2 heads, econo and race. The econo heads use standard valve gear. The race heads have the rocker stands milled off, and you need to install special stands before you can mount the rocker shafts. Did your special rockers include these stands? If they didn't, and you can both them on, then you DON'T have W2 race heads.

no, they don't need special stands, they just use the regular bolts.
one thing...do you know why the push rod studs are off-centered? the roller rocker arms studs were all centered, but the stock ones were off-centered.

Sounds like the '70 T/A heads. They had offset rockers. Can you find the full casting number? we're just guessing without it.

no, they aren't W5 heads, they are W2, but not "race modified"... hey, that'll work for me, still a good head.

Real easy to spot W5s - they're aluminum. If you don't have oval intake ports, then they aren't W2 either. But if they've got rectangular ports with offset rockers, then they've got to be the T/A heads - still excellent.

well, whatever works....
these sure as hell aren't aluminum, very heavy, but they don't have oval ports... go to http://tmezz.mezzweb.com/heads.html to get a glimpse of them...

Hey, that's a real eye-catching color!
You may want to measure those valves. The standard size intakes are 2.02 inches, and the exhausts are 1.60. There are 2.08 intakes available, and some people are now fitting the 1.65 exhausts from the magnums, but 1.85 is bigger than standard big block exhausts.

i agree with 70aarcuda, sounds like a set of t/a heads.( cast number 915 with offset intake rocker) good score! in my opinion i would sell those heads, they usually go for darn near what you can buy a set of edelbrock heads for. i think there is more hp available in the edelbrock heads

hold on, they aren't W anything. W-5's are aluminum. looks like there either t/a heads or j heads since both have a "915" cast number. since you say "stock" rockers wont work on the heads then i'd lean to the T/A's. make no mistake there not W-2 or W-5's

72RR, you got T/A heads, no doubt about it. No D shaped exhaust = no W anything. You have 360 under a runner and offset pushrod holes. That = 340 T/A head = 2.02/1.60 valves = about 800 bucks to a collector or restorer. Sell them and get some real econo W-2's from PAW for $400 a piece. Use your old valve train and exhaust.

W2 Rect port
There are some W2 heads out there that were ported rectangle. They did not come that way. Batten was known for doing this and they made their own version of a W2 in alluminum that I think started life at Diamond. The new Indy smallblock head is a reformed Batten head, you can get it in rectangle or oval port. The easiest way to know if these are TA heads or W2's is this simple question. Do you have an intake that bolts to stock heads or W2's? The bolt holes are moved on W2's to accomodate the larger runners. There is no stock rocker system for W2's. The econo W2 heads will accept the stock holdown and shafts and Exhaust rocker arm.

Leon makes a good point except that the rectangle ported heads are very new. I think, not sure, that the heads are the units with the ribs cast in them for strength.
Can anybody confirm this with a pic from the MP catolog?

well....on the outside of the heads, next to the plug holes, there is a "J" stamped in the head...

you know, i had a couple of guyz take a look at the heads up close and personal (my dad and uncle) and they do have the "D" ports on em'.... so now do i have a W2? they aren't t/a heads, my dad and uncle told me that (they have been mechanics since they were 12)
this is begining to be a real pain, i don't know what the hell kind of head, they work great on the motor, but are they W2's or not?

i as well as others on this board can tell you for 100% those are not w-2 heads. there either standard ol "j" heads available on 71-73 360's and some 340's or T/A heads BUT definitly not w-2's. sorry. you can see in the pic that the heads have a standard exhaust port. and w-2 dont have the reverse j between the sparkplugs.

Ok...take a valve cover off...and write down the casting number...and post it here....that will settle it once and for all...
w2 do not say 360 on them...they do not have a J cast into them... just post the casting number

T/A head?
Just to be on the safe side and so you don't mis-represent the heads if you decide to sell them, measure the distance between the EDGES of the intake and exhaust pushrod holes. On a "regular" head, it is approx. 1 3/16". A T/A head will measure obviously less.
Between the adjacent intake pushrod holes, the measurement from edge-to edge is a bit over 2 3/16". A T/A will measure obviously more. Although it is difficult to tell in the pic, it just doesn't seem like they are machined different then regular small block heads. Myron

Torker don't fit W2
Torker II Dont' fit W2 it's not just the port being out of shape the pattern is different. Go to a MOPAR speedshop and measure the sxtock intake gasket bolt partern than measure the W2. All these questions will then be answered. That 360 and the J are not the number everyone is asking for. There is a 7 or so diget part number somewhere under the valve cover. Also if a stock exhaust gasket look remotely similar to what you have then it anint a W2. I did not see the picture you have.

i have given all the numbers i can see, and read for that matter....
well, thanx for all the replies, sorry for any trouble, paper cuts, or frustration this might have caused but i'll take the car to a shop around here and have a guy look at it... a picture of the heads is at http://tmezz.mezzweb.com/heads.html you can kind of see the intake ports, and you can really see the exhaust...
