Not if he gets his cam timing correct and his cooling system is correct.
It doesn’t take a big cam, it takes the correct cam.
BTW, I’ve been doing some plug reading research and from what I’m seeing, you may be able to cut back on the race gas percentage you are using. I’d leave it the same for the fuel in the nitrous tank, but the engine only fuel is showing excessive leading.
Also, if you are still getting those little wave looking marks on the ground wire you may have a fuel stratification issue.
Easier to see in real life than in pictures though. Just an FYI.
