how do i know when i need valve springs?
 

how do i know when i will need stiffer or better valve springs? or can you even tell?

probaly now since there on sale so cheap!!!

I believe after market valve springs would be a good idea if you are running 50 lbs of boost and a s/w that will let your motor rev past the stock s/w. For insurance.

I read somewhere on this forum that a person needs aftermarket valve springs only if you're going over 3000 rpm's. The factory springs are good up to that point. That's just what I read and if my memory is correct, 'cuz I had the same ??. I'm pretty sure on the info., otherwise I'd have it on my list of future mods. to get.

If you plan on going above 500hp I would advise valve springs.

I would agree, I have seen a piston with valve kiss on truck with just around 500hp. Granted a valve seat slipped loose on that cylinder, but who knows which happened first.

am i over 500hp yet i should be right?

what year is your truck?

I'm on borrowed time!!! Wonder how much the price will increase since the sale is over...got payed today but wasnt in time to order...ugh

hamilton springs will be $349 til Dec 31st, and here's a quote directly from Zach "If you can't get through, p.m. me as such and on monday i will retroactively hook you up with the sale price." you could send him a pm over on compD real quick and see if he will hook you up.
