piston to valve clearence with crane cams quick lift rocker arms?
Just want to double check piston to valve clearance. I wanted to change my rocker arms in my 2000 trans am from stock to crane cams quick lift 1.8 ratio. Would piston to valve clearance be an issue? Part # 144759-16

mrr23, what would you recommend for rockers with my current setup:
Patriot Stage II Ls6 "Style" heads - 2.02/1,57 @ 59cc chambers, running a Comp Cams: 224/224 .581/.581 @112lsa
or what about rockers for the same heads but a Comp Cams/TSP: 231/237 .598/.595 @112+2 lsa?2018 CTS-V: °°668rwhp/658rwtq°°
2013 ZL1: °°590rwhp/576rwtq°°

with your lift where it is now, stay with the 1.7 rockers.
here's how they work and why they make more power than other aftermarket rockers
