Head Bolt Size?

[camas90gsx]

Heres the deal, I have a 7 bolt Non-Turbo Block with Turbo internals, and a 6 bolt Head from a '90 GSX. Im trying to get the engine put together, and am down to the very last bit. I ordered new headbolts, but the ones I ordered were the wrong ones. Does anyone know what size bolts I will need with the 7 bolt Non-Turbo Block and 6 Bolt Turbo Head. If anyone knows, please let me know asap, so that I can the bolts to my mechanic today and FINALLY get my car back. Thanks guys

You need 7-bolt headbolts/studs. What head you have has nothing to do with what studs you need. The threads are in the block. The only issue is using a 7-bolt head on a 6 bolt block, as the holes through the head need to be made larger.

Yes you need the matching head bolts/studs for a 7 bolt block, 11mm

Use the 11mm 7 bolts head studs.

After doing some research, thats what my mechanic and I thought as well, but I just wanted to make sure before we bought new bolts and they were the wrong size again. Thanks guys
