buy the heads and enyoy your new power. the gt40s have larger valves, port volume, and less weight. it would be a good choice

My car is away for the winter now ,and I wouldn't mind trying a set of decent heads.I think our setup is similiar,my e7s are ported and shaved,of course it would be nice to score a set of gt 40s at the junkyard, I would try a set of those i think first.If money grew on trees new afr's would be my choice.

Anyone remember the combustion chamber size of the e7 head? How much realistically can I shave the 64 cc gt40x head to get some compression back?
