If i put my stock cams back in do i need a re-tune????

the difference in boost and n/a cams is valve overlap, which affects how much vaccuum you'll have, scavenging affect, and a few others. The main thing id be worried about is the timing of a stage 4 cam going back to a stock one

When a cars tuned theres also igntion adjustments done in the ecu just a fuel adjustment and thats something you cant change by changing the initial ignition timing at the dizzy or cam gear (if applicable). The other cam differences as the duration of the lift and maybe even the lift its self, try a search somewhere. I can only remember some of it lol
