Re: BB Chevy Intake Manifold Bolts..
[ QUOTE ]
Aluminum intake bolts have a shoulder built into the bolt so not to "dig into" the softer aluminum. Cast iron intake bolts do not have the shoulder..BKH [/ QUOTE ] That go for small blocks? Thought those were shoulderless and used without washers...

Re: BB Chevy Intake Manifold Bolts..
69 Z/28's have a shoulderless, washerless bolt. I believe they use 2 shouldered bolts are for the lift brackets.
