Thread: ZZP XPZ Build

you can get head studs from ZZP, thats where i got mine. make sure the double roller fits on the crank correctly. if the crank gear is out of tolerance the chain will break at some point.

you can get ls7 lifters at the dealership and they are the new factory replacement that you would get from a dealership if you were getting work done. the OE-Rs are just loud and youll always think you have a lot of valvetrain noise for really no reason.

a 3.4 should be good to start, but i was just thinking a 3.0 might be a bit small to be running on a cam only car with no intercooler.

The OE-R's appear to have a design flaw where they come apart. Gonneville a member on other forums posted recently that this is a common issue. Stock lifters would be fine, LS7's are the current stock replacement.

Cam bearings. To do this IIRC you have to pull the crank. Say no to pulling the crank unless you are having a machine shop redo your motor.

Head studs are great. Torque spec is 90 ft lbs. Don't forget the teflon or PIpe sealant goop. (GM or permatex).

Rockers, go stock until you decide to go bigger on rockers.

Springs, the 105's currently on the market will all be Crowe Cam. Stay away from the Mexican production Comp Cam springs. Those are the ones that were breaking. Depending if you went further than 1.6 with rockers, you will need different springs. Say an S1X and 1.8 rockers...that's 130# time.

Head gaskets, use copper rtv spray on both sides.
LIM bolts, timing cover bolts, and the head studs get the Pipe Sealant.goop.

Well after alot of reading last night i completely cancelled my order from ZZP and went to INTENSE and ordered there Stage 4 Heads and Cam package. So even better id say. What do u guys think?

Oh and by the way Bio, i do have an intercooler lol. Stage 2 Fullsize IC
