he just told me today $250 for the heads...going to get a 3 angle valve job $200 and new seals and springs also he will toss in a set of comp cams 1.7 bolt on RR's for another $150. so if I do the heads and put them on with my GT40 intake and 70mm TB would that be a nice gain. would by bottom end be in trouble having tightned up the top end.
