Building a nice street car.

Adam, I think you will have issues with detonation running 11:1 and a smaller cam. If you dont already. Street car means using available fuel. I would add a thicker head gasket, or enlarge the chambers to drop it down to 10:1. Then run a slightly smaller cam, a hydraulic would bleed off more pressure. The exh port is hurting you too. I would not run a single pattern cam with a 60% flowing port. Something like the XE284H. I think for a solid the way to go is keep it larger, like the XS274S.
