I have a set of ported 906 heads kicking around the garage. 2.14 1.81 valves flowed about 285 at 550 and 185. Dual springs for a solid 282s comp cam.10 degree locks and retainers 1.55 springs 5 angle valve job and back cut exhaust valves. Pulled my 4000 pound B body to 114 mph with a 509 hydraulic cam . Ready to run but I realize aluminum is in and freight is high. What to do? Sell or sit on them? What are they worth? Comments please.
