Jerry: Thankns for the reply. I am running all stock intake, block, heads, etc., and I feel confident that when I first took the engine apart, it had never been apart before. All mating surfaces still have planer marks. I did try the intake with no gaskets, and run a feeler around it, and it seemed good. I checked heads and intake with a straight edge and feeler, checked good. I checked the road draft tube canister for clearence, and even elongated the bolt holes upward a little bit, just to make sure.
