I'm looking for a set of good used cast iron heads for big block. I need open chamber because of domed pistons. Looking for bigger valves (2.14 / 1.81) installed and a good set of valve springs that'll handle .550 lift solid lifter cam. I'm not terribly hung up on porting, port matching, blending, etc.. Have been running a fresh set of 906's and would just like to experiment with a bit better breathing. Checking on line through various venues and not coming up with anything worthwhile. If nothing surfaces I've got Aerohead Racing Components cylinder head sheet. Thanks for your time!
