Review on COMP Cams 19024-16 Ultra-Gold ARC Rocker Set - 1.72 Ratio for GM LS1, LS2, LS6 - Pedestal Mount by Sadik Pinger

Used on a 5.3 liter commuter car. Works perfectly! This uses 5/16" pushrods. Comes with sockets and screws. Fast smooth turns and fairly quiet. A lot of people love these! Stock 1.7 ratio, 1.72 ratio is a nice little upgrade automatically. I had to adjust the length of the pushrod measure (do) and estimate the same length as the stock!Although they recommend (and you should) use new lifters to fix problems.They said these rocker arms are designed for LS engines and I believe it ran smoothly .Ultra easy installation and all the information you need to install will walk you through the entire process so anyone can do it.
