    I laugh when people say that. I know a little but I don't know about being "the man"

    What do you mean out of reach, you texted me at 8:30pm last night, lol. I was out eating dinner.

    Check the coil bind and make sure the pushrods aren't too long.
    That combination will work, but as always, check ptv clearance, spring height and pushrod length.

    later,

    sorry for that Allen I was with Gabe last night (from Ecuador) we where kindda desperate lol, will not happen again, anyway we discovered today that the springs that came preassembled with the TrickFlow heads where RUSTED in the place they broke, the valves, pistons, pushrods, etc where ok. So it was a factory error or maybe a bad storage who knows, will post better pictures of the springs soon, I didn´t beleive it when my mechanic called me until I saw them.

    Thanks a lot for everyone´s patience and all your help.

    Red,

    In your opinion (u r the man dude, donīt deny it LOL) would you replace all the springs, or just the worn ones?
