Fastburn Head blind/dead holes?
Does anyone know if the standard (12 bolt) intake manifold bolt holes on GM Fastburn heads are blind/dead or through holes? I found one the hard way that the vortec (8 bolt) intake manifold holes are through holes.
Thanks,
Kevin

Re: Fastburn Head blind/dead holes?
Production heads are blind in the 8 corner bolts, and through in the 4 center bolts (with the pre-87 pattern anyway). I don't see why the Fastburns would be different.
