I have a stock lq9 motor and putting on a set of l92 heads and intake.
What is the max lift that i can run without getting into ptv issues?
And yes i know theres a lot of variables but just wanting to see what others are getting away with. Im wanting to use the ms4 cam, but dont know if the high lift will cause any problems.

MS4 won't fit a LQ4 that has dished pistons, your LQ9 has flat tops adding for even tighter tolerances. Your best bet is to fly cut or buy pistons, other than that stay under 230 duration probably around a 220 and not over 580 lift.
