I want to replace one of my stock valve springs, and I see pace has L92/L76 valve springs at just over a couple of bucks and I want to know if this also works for my L96 (LY6) engine? Anybody know?

thx!

I'd call MAST or TSP.

I was able to have the GM online store look up the right one, so I'm covered. It was only a bit over $2, so I ordered one to replace the one I have w/a bit of rust on it from oil cap off in case I keep stock valve springs. Anybody know how much lift the stock beehives are good for? Mast said I didn't need new springs with the mild cam they have for my L96; would love to believe that.

Well, I ordered it as stated, then found out on second call to Mast that no, you really can't get away w/stock springs with any of their cams. So it was a $3 throw away...just updates so anyone reading this later wouldn't think you could get away w/stock springs.
