I'd recommend taking them to Joe Lapine at Danbury Competition.
Let him set them up for you and sweat the details. He knows what he is doing.
He'll identify any issues with the heads if they are present.
Also be warned, he's going to talk you out of using a hydraulic roller lifter camshaft and telling you how bad the reliability of the components are. He does not mince words. His honesty in the end can be very refreshing.
