i bought a set of head studs from a buddy of mine, the head studs are from a LS2 head, whereas i have a LS1 head. I need to find out the stud size for the 4 shorter bolts on each head (1 front and one rear short bolt for each head). ARP has tried helping me but said I need a measurement. Texas-speed also hasnt responded to any emails. Anyone have a clue?

actually, is the head stud gonna be the same size as the stock head bolts? i was thinking that the length may be different.

ok, reading threads and I need to verify. I read somewhere that the LS2 head studs were all shorter than the LS1 version. Is this the case? Anyone have any ideas? I guess TSP and LS1 speed are all closed this week or something... ARP didnt help much.

thanks Ray, but i got it figured out. the LS2 blocks head bolts arent drilled as deep as the LS1 block, so Adam's studs are too short for my block. gotta get a LS1 kit instead.

Not to thread hijack but I was wondering when you use head studs can the heads still be removed with the motor inside the car?

How do you determine what year block you have? Mine is a used lq4 if that matters.
