sorry, as I was saying...... Anyone know the diff between a 1008 and a 8553 felpro head gasket?

8553 is a stock replacement gasket, 1008 is the high performance Perma Torque gasket with the steel wire fire ring.
The other difference is the price the 1008 ain't cheap. |

I'm assembling my 340 with new edelbrock rpm heads and I installed them with the 8553 gasket. once I installed them I measured the compressed thickness at .045. Didn't seem right and I noticed the 1008 is .039 installed. Thankful I noticed. Still on the stand so I can still change em no prob.

the 1008 gasket has the steel wire ring for high compression engines if you have a stock rebuild or low compression you dont need 1008

Its a 340 with 10.5:1. I ordered the 1008's. I don't want to loose any compression with the taller head gasket. I'm running aluminum heads.

HI I AM RUNNING THE EDELBROC HEADS MYSELF AND I HAD PROBLEMS WITH THE 1008 FELPRO HEAD GASKETS THEN ENGINE IS FRESH AND HAS BEEN DECKED I WOULD RECOMEND GETTING THE DETROIT HI PERFORMANCE HEAD GASKETS THEY ARE BETTER THAN THE FELPRO GASKEST OR RUN A SET OF COMETIC HEAD GASKETS AS THEY R THE BEST YOU CAN BUY AND THEY ARE REUSABLE ALSO

|
||||

||||
|
||||
So what gasket should I use? I still have the 8553's on it but have the 1008's on order. I don't want to loose compression so I want to put on the 1008's. The block hasn't been decked.

get the detroit performance series ill get you a part number tommorow or monday and post it for you another peice of adviced for the edelbrock heads the tourque spec on those heads isent enough torque them to a 100 ft pounds at a min 120 max and use studs not bolts the i had sealing problems with the 1008 at 90 pounds torque so i was talking to i think brodix and they said it was to light in the torque department so i bought the detroit gaskets and put them on and torqued the heads to 110 ft pounds and no problems the 1008 you can cancel or return them i paid 26 bucs for the detroit hipo head gaskest so their not over priced like felpro is the only gaskets i usw from felpro is the 1213 intake and there oil pan set in the race hope i have helped you out later

The arp head bolts instructions recommend 75 ft. lbs. for aluminum heads due to there expansion rate with there moly lube. Also they recommend torquing and loosening them i think 10 times before the final torque to "seat" the threads. You're saying that's not good enough?
Anyone else have issues with head gaskets with the edelbrocks on a small block? |

studs hold better dut to the faact that you have 2 calmping forces working for you plus the fine threads on the tourqe side of the stud is more accurate in tourquing than course threads im just telling you of my experince and a couple of others that i know that had the sme problems as i did and that was the cure

I was running coppers with just an o-ringed block but with a learning curve with the turbos I decided to stick a fuse in the equation. The 1008 held up to 10 psi of boost on my motor(ther o-ring rode just outside the fire ring) Even on a pass running so lean the motor fell over in high gear...not good.
Three passes later with 2 psi more the gasket let go...6.64 1/8th at 105mph at 3500 lb Never had a problem with the 1008 on motor alone.....head was studded... |

Waldo, just wondering about the "reusable" part. Is this a claim by Cometics or a personal observation. I have used the Mopar steel shim gaskets over in emergencies (middle of the night on race weekend to make doubleheader) by spraying them with coppercoat but never more than once. Just curious.

well i have seen some of the dirt boys reuse them 4 and 5 times i also went to a ford drag meet in columbus ohio no ragging allowed lol my best freind is a ford guy so we go to ford and mopar events togather and we watched a couple of pro 5.0 guys rip the heads off of their turbo powered and nitros injected engines and then put new heads bac on with the same exact cometic head gaskets that were on the engine to begin with so i honestly do believe that cometics claim that they are reusable is gospel supposedly there just as good if not better than o ringing and using copper head gasets so on my next engine im using them and they require no sealent at all to use just stick and go hope this helps you out

On a simular note, I have edelbrocks on my 383 with the Fel-Pro Hi-Pros and I run Nos on arp bolts. I have been doing this for 2 years now and havent had to pull a head once. Edelbrock gave me the torque spec for there heads with arp bolts and has been good since day one. Now Im not saying this is a good route to go, But it worked fine for me.
The reason they tell you to use the hi pos is the the expansion and retraction of the alluminum head tears apart the cheap papers. I by no means would run the paper. My brother had the papers on his 8.8-1 383 and after 2 bottles of a 125 shot the gasket failed. We know it wasnt a lean condition beacuse the pistons were cast and didnt have any sighns of lean, also we replaced the gaskets with the hi pos and ran the bearing out of the motor 3 years later. |

What about the MP P4120094 gasket?
I am about to install these on an all cast iron 360 that is 10:1, they install at .024 and are rubberized. Anyone use them yet? Can they handle mild abuse? They look trick and install like a shim, they were cheap too. Who makes them?

I just got my 1008's from MRE. I'm going to use these. I will make sure to retorque a few times after racing just in case. We'll see. Thanks .
