I need some help.. I'm trying to make 650-700 whp out of a ls vtec setup. But I need to know if arp main studs are needed for those power levels?? Also will I be needing a gridle??

I also just picked up some skunk 2 pro 1s but idk if my valve train will be sufficient enough to support.. It has crower valve springs and retainers but idk if it has aftermarket keepers of valves.. I bought the car from my buddie who had the engine built along time ago and never put the car together.. Should I take the head apart too?

Thanks guys

 

When shooting for 700whp you shouldn't leave anything to chance.

 

at those power levels even the smallest oversight will cause issues.

if you think you need it you probably do

 

Yea I was thinking the same.. The arp mains will probably be a must for sure.. Not sure about the griddle.. And I'll probably replace the keepers because ima be furious if the **** drops a valve and destroys my engine!!
