Find a good set of used E7's, port the exhaust sides out on the roof and walls, blend into the bowls, remove the Thermactor bumps, leave the floor alone. On the intake side just smooth any rough edges and blend the bowls. This makes them closer to what the GT40's are and do well on a mild buildup. I did a set 4 years ago and my only cash outlay was for the valve job (they used a Serdi Machine to face the seats) and new springs. Paid $50 for the heads. Altogether I had maybe $200 in them. You can mill them .030 to decrease the chambers to about 58 cc.
thanks for all the advice guys, much appreciated.... i'll let you know what i get and how it turns out.
