Not sure about the COMPs. I have heard nothing but good things about them but the patriots are a high quality spring as welll. Its the Cranes that you need to look out for as recently their seat pressure has been slightly low (A sponsor/vendor told me that when I ordered my cam).


I dont think you can go wrong with COMPS or PAT's and seing how you will need to swap springs every 20k Id make the economical decision.

There has been no recorded failure of Patriot "GOLD" rings yet. IMO PAT's are the way to go.
Depending on which cam you go with, they will have to be checked and measured every 15K but not necessarilly replaced

Hey Predator, how hard is it to check the springs once on the car? I ask this, because I still havent dropped in the LS1. I know on my 3.4 its a royal pain in the ***. TO remove the valve covers, you have to remove the intake plenum, fuel rails, injectors and a few other things . I've seen some people mount the coils on the shock towers, which my guess would be to speed up removing valve covers. I dont really want to have to do that, so how hard is it? Simply unplugging the plug wires then removing the valve covers?

Thanks,
David

remove coil packs
remove valve cover
remove valve spring (use TDC method)
check spring pressure

thats the simple gist of it.

Yeap, what he said

I would just add disconect battery first (That should be common practice)
