Need Advice on head bolts. I have a 454 V1 with aluminum heads. Bought headers and they hit the bottom 4 head bolts. Their about a 1/4 inch too high. So I need to change to a lower profile old type hex bolt. Any advice? I believe I still need to have washers under the bolt.
Anybody have this problem?

thanks in advance
Doug

Dan'l did you have this problem with aluminum heads?

thanks!!!

No- logs and snails cleared fine

Yeah, needs the hardened washers.
ARP bolts should fit, pending whats in there now.
