I heard there is going to be a iron version of the fast burn head (vortec?) avail. for $450.00 pair complete. I want to know if I can use these heads on a ZZ4 short block and the HOT cam. Also what manifold would I use and and HP predictions on this set up. Would it be the same 430hp as in the ZZ430 motor at a much lower price?
