stock ls3 valve springs max lift
hi all
just a quick question
how much lift can the stock springs handle before the bind up?
i know i should change them out to some patriot's but a head swap is coming up son so i would rather wait
the cam i have chosen has 590 lift
and ill be fitting the new head out with 1.85 ratio roller rockers
thanks

No. That cam is designed for stock rockers. What little you gain with the 1.85 rockers will be offset by valvetrain instability, reduced spring life and lower compression ratio.
I don't know your entire build, but it sounds like you need to do a little more research before you start buying parts.
If this is going on a stock, ls3 short block, .642 valve lift on a 2.165 valve is not going to go well together. That valve is so large, you quickly run out of real estate between the piston and valve.
