So my heads just got finished. Valve sizes are 2.02 & 1.60. We wound up getting 299.88 intake & 203.38 exh @ .600 lift. I am very happy with the results and can't wait to get this beast running! The guy Lou who did the porting is awesome, he does it old school completely hand ported. Bang for the buck nobody came remotely close... Which was a huge part of the reason I went with him, that and his reputation. Being able to save money there was great as it let me be able to afford some other things like having the intake ported and going with cometic gaskets.
