Roller Rockers 1.5 vs 1.6

How do you decide on which ratio to get?
I didnt get any when I purchased my aluminum heads but now SM has all the SS rockers in stock ( well kinda...) so since they haven't had any in 7 months I think I may pick up a set... I kinda want 1.6 for a little "extra" lift from my cam but worry about valves hitting pistons?

Assemble everything and clay your piston tops, turn the engine over by hand, disassemble and check clay thickness.
Yeah, it's a lot of work. This way you know what you've got.

I can't remember the stuff we use at work. It's some sort of machining clay for checking tolerances like below.
