Well, let's look at it from the $$ side of things since that seems to be of interest.
Switch to roller cam = new billet cam, new roller lifters, new push rods, new valve springs (after all, what's the limit?), camshaft movement limiter of some sort, roller rocker arms, and then add in the machine work to allow the new maxsize valve springs that will be the next on the list to be allowed.


Reduce max seat pressure to something that will live with flat tappet lifters = new cast cam to work with the reduced pressure, new flat tappet lifters, new valve springs.


If you are smart, lobby for spring pressures that will allow common auto parts store parts to live. But I forgot, it takes too much to figure that out.
