I had fel pro blues in my 416 sb with 12:1 static compression. I blew #4 into the lifter valley on Friday at Island Dragway. Do i go with the fel pro again and right it off to too much timing,,,, which I had just advanced a few degrees,,, or is there something else I should use? It has eddy heads. It was a hot day, 95 degrees, and I did make alot of passes, and I did throw some extra timing at it... I know I know,, a recipe for disaster... and the recipe worked. HA. How about head studs,, would that help any?
