I know this is an older video, but incase you were still wondering about valve seats on VP heads, the hardened seats were only on the HO motors. The intake floor hump was there to clear P-pumps in other applications, from what I understand.

Have you dealt with any aftermarket blocks, heads, or cranks? When I do my 6.7 build I want to buy new so I can stay standard bore easily and minimize how much the block and head are surfaced, but the aftermarkets are much less expensive, mainly the blocks. My local machine shop that deals with a lot of commercial and industrial stuff has sold a few with no issues. He said they are usually heavier because they build up problem areas mainly in the heads.
