Agreed-even I'm unsure of the direction the heads will take. Like I hinted at earlier-I may "bust the budget" on the heads. I may-just may either try and use the G3 Hemi valves or I may go 11/32" Chev 2.02"/1.60" . The only thing I know for sure is Magnum castings will be used and I will try and illustrate how they can be repaired. J.Rob
