ok so i have a 95 z6 block, with a 96 y8 head.......the rest is unimportant for now, but i have searched many places to find the correct info on what headstuds to use.....i found one source that said it was the y8 headstuds, so i ordered arp y8 headstuds......i got them brand new yesterday and screwed them in, and when i slide the head over them only a few are long enough to even start putting on a nut and washer, but 6 of them arent long enough to even come all the way through the hole.......so am i doing something wrong or do i need different headstuds? sorry if i sound like a jackass and thanks for the help!

 

what is the arp part # of the ones you bought?

 

208-4305 is the part number

 

one end of the stud has more thread on it than the other,you try flipping them around?

 

btw..I used 208-4301s for my D16Z block + Y8 combo,I had to use extra washers on two studs cause they were too long,the rest were fine.

 

ya i tried both ways, but i talked to some people and they said i should use z6 headstuds and not the y8 ones i have.......ill get some overnighted and it should be all good! thanks for the help dman

 

you might need two studs from that Y8 kit so you dont have to run washers on the new Z6 ones..The one with the Z gets 2 extra washer,the X gets 1 extra if you use all Z6 studs

intake side
Z O O X
O O O O
exhaust side

Try two of those Y8 studs in Z and X and see if this fit ok
