302 heads with 671
What would the best heads be to run on a 302 with a stage 2 bds 671? I am running the stock heads from a 1970 302 with a bds blower cam and stag 2 blower 18% UD now but I think the head gasket in going, i am getting alot of pressure build up in the radiator.What is a good mid-grade head? Can I run a set of gt40 heads? What cc, springs, and valves? Are blown head gaskets a common problem for blower motors?
