Dang,.maybe I have something wrong in my numbers. I haven't bought anything yet, except the rotating assembly and the heads. So the HG and cam can be altered once actual compression is measured. But I do know the pistons are out the hole .018.
Well the piston to head clearance will pretty much dictate what head gasket you need to use, so with what you have at the moment, you will be around 9.8:1.
I'd think a 224@50 Flat tappet hydraulic would be OK for that sort of comp and induction.
