Milling big block heads?

I have a set of angle milled 346's off my 440 that I ran for YEARS. What would you like to know? The chambers are at 78cc right now and I ran a SpeedPro 11.5:1 piston with them. Yes, the valve notches had to be re-cut. Yes, the intake had to be cut and used only with a bellypan gasket. Solid cam, STOCK length pushrods. Made over 100 passes. Valve tips look perfect and do the Crane ductile iron rockers.
