I have the 233/239 .595/.605 112lsa cam from TSP. I am about to slap on a set of PRC 5.3L Stage 2.5 heads. I am currently running the 918 springs with my stock heads, the PRC's come with PRC double springs rated to .650 lift. Should I swap my 918's to the heads or keep the PRC springs?

Also, will my current pushrod's be the correct length for the new heads??

Duals without a doubt. Anytime you go over a 590 lift I suggest goin to a dual spring just for piece of mind.

Patriot offers a full kit for $255, but since your goin TSP, just add the dual springs to the heads.

If your not gona check the springs like you should, then go with the duals. But the singles are sufficent.

with that profile, and assuming your are going to turn the motor over 6K, diffently duals.
