SB head bolt question

duster340, it's a BDS 6-71 huffer set up to run 6.6% overdriven, [font=Verdana, Geneva, Arial, Sans-serif]5.5 - 6.0 Boost, 11.5 final compression ratio with 8.0:1 pistons. I figured that would be a safe start. Using two Holley 600's also.[/font]

Those are factory spool mounts in the photo. I'll probably go the polyurethane route too.

moper, the manifold looks to be an aluminum single plane four barrel intake that's been retrofitted for the blower case.

Thanks for the input guys :)
