What springs come on eddy performer RPM heads

I'm going to assume the worst with a piston down hole .060 (typical) and Fel Pro 1008 head gaskets with 8.77 cc's. This is going to yield a whopping compression of 8.6:1. Unless your going with a small roots blower, stay away from the Crane 693801. I would run this specific Howards cam, advanced to the point of building maximum cranking compression.
