it WILL float the valves. I'd suggest going to a spring stronger than 918's since I floated on the 918's before.

what strong get the 918's i know the 921 but thats a pretty penny

My personal preference would be the PAC 1518 springs shimmed to 145# seat pressure.

Texas Speed PRC dual springs ..the ones that are rated at .660 lift should work well. Those or patriot golds are both similar caliber springs.

thanks for all the info i think im ganna go with the patriots but here is my biggest issue how do you do it with the motor in the car the first 2 on each side look easy the last 2 look horrific

this is what I used, well, I made my own but basically the same tool https://ls1tech.com/forums/tools-fabrication/317675-tim-s-valve-spring-tool-now-available.html. It's simple and cheap, you can do all the springs fairly easy with it. Do you have an air compressor to charge the cylinder so the valves don't drop?

witry

iTrader: (8)

yeah i got the compressor and the fitting to go into the plug hole to keep the valves up

witry

that tool is like a tool from god you got any leftover to get

Contact the guy that makes them in that thread, I'm sure he can set you up with one. And the two rear ones on each side are cake with that tool.

My buddy was able to pick up 50rwhp by changing springs and pushrods. It was floating the valves and the spring change put an immediate end to that. Stock LS1 with just the springs, auto trans, 12-bolt rear - 500/500rwhp/rwtq on a little under 9psi. STS kit with a big turbo.
