Thanks for the replies. I really do not want to have to be adjusting things every 2500 miles, so I think I'd best stick with hydraulic flat tappets. Either that or go hydraulic roller.

I guess then the question is - will a hydro flat tappet setup allow me to use a cam profile agressive enough to hit 350hp?? From what you guys are saying, the answer seems to be yes...?

I have no intention of going anywhere near 600hp with this. 350, maybe 400 is what I want. So if I can do that with hydro flat tappets, and not have to worry about adjustment every 3k, great.
