Dual plane to single plane track test in the works

I’m in the process of installing my TF’s with bigger solid cam on my stroker. Plan is to start with the Air Gap and see how it does for a while after proper tuning then try that modified M1 single I have. My testing will be done at the track, I’ll see how things shake out.

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.
