Performer RPM Magnum heads?
For a 410 stroker Magnum I bought the Eldy Performer NHRA Magnum heads from Mancini on a 'Black Friday' deal. Mild cam as this is my non-hotrodding wifes 78 LRT. I paid like $850 for the pair plus Mancini's stupid shipping
Port work was trash with a lot of core shift. Oil drain back holes were 3/8 inch. Casting flash everywhere.
I cleaned up the ports and gasket matched a little, made the transition to the valve seats more tapered. All oil drainback holes are now 9/16 or 5/8 inch
