Has anyone bought or sold a pair of used stock 454 Mag or 502 mag, (bigblock-square port) heads lately? If so, what did you pay or sell them for?
Thanks,
Gordo

I bought a pair for approx $550.00
I have several pair that I may be parting with in the near future.

I have two sets off HP500's with valves installed and brand new ISKY valves, retainers and locks still in boxes that I am looking for $600/set for.

Going rate for a good GM head casting (large oval or square) ready for your own valve program is $200 each around here and going up as the supply decreases. --- Jer
