I think .035 is too much, I'd say about .030. We ran .026 on race fuel. I'm not sure what GM gaps theirs at stock.

In a recent thread on this topic gaps ranged from .022 to .038 or so. Might have been one in the .040s. Mine are .028 on GT100.

See https://www.camaro6.com/forums/showthread.php?t=601681 Actually, that's not the biggest thread but I don't see it

Depends on how much boost. Around 15 .30 to .32 is fine, start to
Hit 16-18 and I would decrease it down to .28
