Junkyard BEAST!

can anybody actually recommend a shelf grind from comp for this?

Was playing with camquest a little and was thinking one of these
XR274HR-10
dur at .50 224/230
Lift 538/534
LSA 110
RPM range 1800-5800

Or this one, a little more aggressive...says it needs 9.5:1 compression, dont think ill get that though
XR280HR-10
Dur 230/236
lift 541/537
LSA 110
rpm range 2200-6000rpm

both are hydraulic rollers...not sure if im on the right track though?
