If they're the comp pro mags and you pass on them let me know. I have a set of the pro mag 1.75's that I want to trade for a set of the 1.85's.
PTV means piston to valve clearance. If the heads are milled and depending on the valve size they could touch.
Lift would be right around .610
Max lift for the 918's are .600 or .625 if you have the newer version.

lift...
.561 / 1.7 =.330
.330 X 1.75 = .577
.330 X 1.8 = .593
.330 X 1.85 = .610
i was told with the 918s...even the old ones that i have...max lift is .620 or so. but .610 would be pushing it. may as well spend the $$ and get patriot duals to handle .650
