magnum heads, 10.6 to 1 and a mild cam?

I have been using the wallaceracing calculator for the dcr calculations. Still shows the same calculations. Don't forget that I have the ivc (61) set 4 deg retarded from the 106cl comp grinds them on. As for the heads I have adjustable valve train, roller rockers. The heads are good to .540 lift. At .540 lift I have .050 clearence between retainer and valve seal.
