Dual plane to single plane track test in the works

i honestly wouldnt even bother with the airgap with your heads.
Mine was done about 6400-6500. Refused to pull past that. I know there was zero issues with springs, etc, etc. highly suspect it was the dual plane as the culprit.
I don’t doubt you. It’s just that I want to see what the airgap does at the track being my carb is dialed in with that intake although I know with the different heads and much bigger cam I’ll have to do some tuning. I just wanna see what kind of tuning I’ll have to do but at least it’ll be in the ballpark for the dual plane. Then I can put the M one on and go from there and see what it does.Mainly it’s for my own personal satisfaction to see what I can do with both.
