ok so ive searched a few times but its hard to get a for sure answer.......

d16a6 block
d16y8 head
which arp headstuds?

right now im running z6 block and y8 head with z6 studs......i got y8 studs first and they were too short, so do i use the z6 ones on the a6/y8 combo or the y8 ones?......thanks

 

Ae you sure they were Y8 studs? I have always known to use the head studs for the head. The blocks are the same so I don't see how the Y8 studs wouldn't work.

im like 100% that they are z6 studs......i ordered y8's thinking the same thing, but they were all too short.....apparently y8 headstuds are 80mm.....and z6's are 100mm.......so im not really sure

 

i did this setup once. i'm pretty sure that i ordered the headstuds for the z6. one of them stood up too tall to allow the nut to torque down properly. i took the factory head bolts and cut them to get the washers off. then i covered them with arp lube and stacked 3 washers on that stud. everything torqued down just fine and we never had any problems with the motor.

good ----.....i just ordered my eagle rods and vitara pistons

 

maybe u have a z6 head? cuz on the y8 ONE stud is supposed to be shorter.

 

well if i had a z6 head then my obd0 dizzy wouldnt bolt to it, it wouldnt say 98 on the casting and some other obviouse things.....there are 2 studs that i used washers to make up for some length differences....
