Correct Direction

Right on with everything, especially the late 5.9 hydraulic roller cam available blocks and getting those heads ported. Most of the ones I've been directly involved with still have a good bottom end but since you've got H beams it appears you're going past stock, so I'm curious as to what pistons everyone recommends. (I would probably go with some Speed Pro hypereutectic flat tops). Add a high volume pump and chromoly intermediate drive with an applicable pan and pickup and it's golden. On the cam, get a set of Crane replacement hydraulic roller lifters and call Ken Heard at Oregon cam grinders. He may have a grind specific to your application that he can put on the core from you engine, but he may also recommend an aftermarket grind that better matches your needs.
