7000+ RPM hyd. roller motor?

[CRIPPLED PONY]

I use the crane power max--244/256 @ .050 and .595 across the board on the exhaust lift. Its rated for 7000 rpm plus. I take it to 7000 with no problem. I just don't push it past it because of my own personal preference

I know I asked a simular question before but is there any one out there that is using a non-stock hyd roller lifter that is having good results past 6500rpm? Like the comp cams pro magmun series. If so, how much were they? the reason I ask is that I am having a 331 built and I got the TFS-R intake, and every dyno test i have seen says this is a real high rpm piece. I think I may have over done it.
