    you are just wasting hp using 95lb seat pressures on a N/A car
    even on the normal beehive we have safely run 35psi of boost without valve float
    obviously some haven't done their homework

    Indeed, with these i will have more seat pressure than needed. Was hard to predict, because i am using the Ferrea SG valves/locks, with the Crower retainers, and i would only find out the install height with the springs in hand. It would be the same with the Supertech springs, i can only check the install height/seat pressure with the springs in hand. At least, there is no cam that can get these close to coil bind.
    But do not forget that it's not just the engine type, it's the setup too in my case that needs good valve control because any miss even slight and the valves will hit the pistons. If you remember, pistons sit flush with the deck at TDC (almost).

    Yes, M\A is performance oriented we just don't need the BS from people in the peanut gallery.

    P.S. Look in the mirror.
