Title: CORRECT HEAD AND INTAKE BOLTS FOR A 69 Z/28
Post by: baldeaglemtnman on June 05, 2006, 10:15:58 PM

Can anyone tell me what the head and intake bolts look like and what are the correct markings for each?  Are the bolts for the 302's different than the other small blocks. I thought the intake bolts were a standard hex head (no washer) Grade 5 with an "M" in the middle. Someone's tying to sell me "NOS 302" intake bolts that have a recessed head with an "H" inside a "C" with the built-in washer style head.  Any info would be greatly appreciated.

Head bolts typically have a "circle" headmark. Aluminum intake bolts are plain hex head (no flange or integral washer), typically with "A", "TR", or "M" headmarks; lock washers were not used.

Thanks for the info John.  So head bolts are head bolts---there are no "special" head bolts for the 302's?

Nope - there was nothing special about 302 head bolts - they used the same bolts as any other small-block.
