I have a 96 Z28 cam waiting to go into my L05 (hopefully within a month or two) and I was wondering what valve springs would be good to run with this cam. I would be looking for something around what a Z28 would have had stock, except that fit my L05 heads. I don't want to over-spring the valves (HP loss) but my 167k L05 springs probably won't do the job past 5000rpm.
Any ideas?

I'm using the VSA 1 kit for with my Ram Jet cam. $30 for new GM springs/retainers/keepers...not too bad. You might want to go one step up if you plan on revving higher. I don't plan on going past 4800 rpm.

Originally posted by kevm14 Thanks for the link. I think I'd want to go with the VSA 3s. Do you know what the seat diameter is for my VIN 7 L05? Is it 1.25"?
I checked the stockers in the basement and they are, indeed, 1.25 diameter.
