Looking into getting some 1.6 roller rockers and valve springs and would like to know which company to buy from and the part numbers. Anything else i should consider changing ex: pushrods, retainers, etc.

 

If you're still running the stock cam, the LT4 springs are cheap (around $30 a set) and will do fine with the 1.6 rocker/stock cam setup. GM performance has the Crane 1.6 self aligning roller rockers that will work great, and they even have the little bowties engraved in them!

 

Thanks for your help Josh. Does GM Performance have a website or do you know there number?

 

While I don't have part numbers, I do have the Comp Cams Pro Magnum 1.6 roller rockers and Stock length Chromemoly pushrods. I love the setup. The rockers are 3/8" studs, self aligning, and the suprising thing is that they're whisper quiet. I've got no valvetrain noise at all.

The Pro Magnum rockers are popular because they're chromemoly, meaning they're light and strong. Ditto with the pushrods.
