Dear Redheart,
The heads R 62cc combustion Chamber, I'm guessing the OEM is around 58cc or 60cc....but u r the master here
If I send a valve to meet a piston, wont that bend a valve, or a push rod, but not break a spring, thank for ur input and please guide me here.
Also the Cam ant the turbo sys and almost every mod was consulted and aproved by Allen. But as ussual, he's out of reach

Even the stock LS1 springs can't handle that much lift. How much lift are the springs on those heads good for? Did you clay the piston tops for clearance before you finish torqued the heads on? Checking the piston to valve clearance is very important. If you have the heads off be sure to check the clearance this time around.

I see its .600" max lift.

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.But as ussual, he's out of reach
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.
