Robby1870 Posted January 20, 2006 Report Posted January 20, 2006 You would use a 3100 head gasket, since thats what pistons are in the engine. Quote
1990lumina Posted January 20, 2006 Report Posted January 20, 2006 PM GP1138 (John) or wait for him to chime in here...he's done this swap before Quote
dbtk2 Posted January 20, 2006 Report Posted January 20, 2006 You would use a 3100 head gasket, since thats what pistons are in the engine. Or use the iron head 2.8 head gaskets to bump your compression up...thats what I would do. Quote
White93z34 Posted January 20, 2006 Report Posted January 20, 2006 its not a overall hard swap, you say that you have a 95' prix. when was the car built (on drivers door st production 1995 cars, pull off one of the rockers and studs if there is a little notch under the rocker ticker) the reason i say that is about the rockers. since its a 95' it will have the stamped rockers which will not clear the 3400 LIM, now what i saw they used the roller rocker style heads on latehen you can use the newer style roller rockers on your existing heads. but if its a early 1995 car chances are that it has the older heads which simply do not have that notch.

THe_DeTAiL3R Posted January 20, 2006 Report Posted January 20, 2006 I think he might be changing his heads to ones from 3400, since he asked about the head gaskets.. Quote

GP1138 Posted January 20, 2006 Report Posted January 20, 2006 FWIW: I used a whole re-gasket kit for a 3400, and it didn't make any difference, the car runs great, no other problems. Quote
jolly4numb Posted January 20, 2006 Author Report Posted January 20, 2006 ok, well i just called my dad and told him to pick up the the 3400 re-gasket kit he said he'll pick it up today... thanks alot yocum Quote
