Default What Valve Springs to use with Trex
Just like the title says I'm guessing there's no way stock ls6 yellow springs will work???

Comp 921's or PRC gold extremes should do the trick.

No way the LS6 springs work. I used PRC Golds with my TREX with no issues.

.608/.612 lift on that cam. And like said above, the patriot extremes will work well for that cam.

I would buy the best springs you can afford. I have a computerized spring checker at work. I checked a set of budget springs and found them to be inconsistent.

Well, if you consider 200$ budget, then i guess i may have some inconsistencies. Otherwise, the specked out great at the machine whop and actually had more open pressure then advertised.

I don't know about the ebay springs and I'm not going to start naming the brands I have checked, because I don't have the time to argue.
