I left off the Vortec cast Iron head which is a good head that You can buy new for about $520 for a set. You may have to change the springs for your cam. The old 186 or the 041 heads would work good as well.The 292 turbo is an excellent old chevy head as well.I am assuming that you need the bolt holes in the front of the heads . If not the old 461 0r 462 with hardened seats would work well
