I'm currently working on a NA max effort SBE setup 6.2L that's got a healthy cam ported And milled L99 heads on pump gas making 512rwhp 469rwtq through a 6L80E.
My thoughts are swapping to those PRC LS7 small bore heads and run a MSD Atomic intake manifold. Are those heads worth any over a ported set of L99 heads? Any feedback would be appreciated.

Yes they should be as long as you cam them right.

I personally like the swap interesting "max effort" how much compression, what fuel are you using and torq converter as this trio is crucial.
Happy new year....

Mine made an assload of power. The LS7 valve angle and intake are the keys. Side bonus is you get to use thick 3/8 pushrods and the better geometry ls7 rockers

Still waiting to see a LS3/416 w/ SB's LS7s. Something other than a drag engine.
