Boosting a LY6. Bottom end plan is to regap, may do new bearings, head studs, rod bolts. Going to run the stock VVT cam for the moment.

~ What are good valve springs, stock rev limit, but need enough to keep them shut with up to 20psi? Are the stockers any good, to what extent, 10psi, 15, 20, ect?

~ I believe I have read that these heads come with Inconel exh? Can you verify this?

~ Any other worries on the OE valves with boost?

With upgraded springs should I be worried about the rocker or pushrods at all?

~ Am I overlooking any valve train related items that need to be addressed for longevity?

Thanks in advance.
