So many knowledgeable and experienced people here know what works
Gotcha, I just meant I couldn't see pulling the heads this winter and then upgrading the cam next winter ... makes more sense to do it all at once.

Now for some really crazy talk ... would a procharger eventually benefit from the porting and cam change? My gut says yes - you can get the same mass of air/fuel into the engine at a lower boost PSI if you've got more port volume.

Yes, just look at boost like a multiplier, more power NA= more power procharged/roots/whipple/turbo etc

Do it all at once. It has to work together. Pushrod length, spring installed height, etc.

Think you’d need a different cam if you went boost.

Exactly… just got to decide, that cam would be a definite. With port work…and intake.
