well obviously the lift is one of the main things to look at, bc the 1.8 increase lift. i would think you would want to stay at or around .600 lift and checking PTV clearance would prolly be a smart thing. very simply though i dont see why a tr224 .564/.564 wouldn't be fine for your app.

Cam vendors suggest against using the 1.8 rockers for most aftermarket LS1 cams:

I think the 1.8's are recommended for less agressive lobes like the stock cam. I would pick the cam you want and put the stock rockers back in.
