You are welcome. Any feedback on why you prefer the single valve springs compared to duals?

I will only go dual from now on
KB: my logic to go single was I didnt want a heavy noisy high pressure springs beating up cam,valve seats,cam bearings.

1) cost
2) not planning on revving past 6k ish
3) ease of install.....supposed to be a drop in replacement (on an ls anyways)
4) a bunch of the ls guys making way more boost have run these for a long time
5) seat pressure as compared to duals....lower = less wear and tear
I was told that these were approx. cam specs
L83 .500/.490 lift
L86 .550/.550
LT4 .490/.551 120 lsa

Cost is a restraint on this project.....built engine would be another story
any details on your Silverado?
fwi: I don't see the 1211's listed on the pac site anymore?
