Heard these are a good upgrade for Vortec heads, I have 1989 Caprice 9C1 Police car heads. They are 64cc chambers, I'm told they are the same heads on the Corvette of the same year. Just going with like a .447" lift but want some new and decent springs.

Duh forgot the question, think these will work for mine?

Can't view that auction from where I am.

Best bet IMO is to work with whoever made your cam, and who will supply your springs, to come up with the right ones.

I'm sure flat tappets are the same as rollers in that regard, although perhaps a bit less "picky"...the cam manufacturer recommended springs based on the cam grind for me.

yeah no reason to mess around with cheap stuff, I'll just call Comp. Mine is roller as well, there is some considerations with that and valve springs too.

Roller cams require stiffer springs. The ramps are much more agressive and require special springs to prevent valve float.

As stated before, get a matched package with your camshaft.

I usely go with Comp Cams. I like to get the "K" kits.

wow just looked up the K kit for the cam I was thinking about. $975! What does it include???

K kit parts list

I'm guessing a LOT of things you don't need/would end up overpaying for, when all you want are springs.

I guarantee as long as that kit includes roller lifters, a large portion of the price you quoted is going to be for replacement lifters.

Thats one of the great things about roller cams...you can reuse your stock lifters.

As I understand it, factory roller lifters are superior to all aftermarket options.

i use these springs in all the heads ive had rebuilt. work great and cheap. the local machine shop sells them to me for $16 a set. i wouldn't use them for a roller cam though.
