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?
Build...
30 over 340, pistons all around .012 out of the block

SM CNC fully assembled heads (pictured)
I know I know buy the expensive ones that are "better..."
