I need some help finding/choosing a shelf grind from comp. To make a long story short I have tons of gift cards for amazon so I can't but a tsp,tr, etc. cam. Has to be shelf grind.

I would really like a 228r so any specs around that would be awesome.

This is all I have so far

XR281HR 228/230 .571/.573 112 LSA

XER273HR 224/230 .581/.588 114 LSA

XR275HR 222/224 .566/.568112 LSA

I'm not really sure what the difference between the lobes are, besides ramp rates which I also have no clue about..

I really like this cam but I think the lift is a bit low
XR277HR 224/228 .534/.537 112 LSA

Are there any other shelf cam's I'm missing? Can I run behives on any of these? Which one would have a stock length pushrod(I already have hardened pushrods, Can I reuse them?)What gears would I need for most of these cams? Shift points?

Car is 6spd ls6 intake/exhaust/tune and MAYBE a 100-150 shot. Daily driven. Looking for most usable power here.
