Great! I'll try and do the later head. What does 1/2 or 5/8 reach actually mean.. is that saying the former is less recessed and the measurement from spark plug tip to face of head?

And what is your thought for why the later 1935 head has more restriction in the transfer port? What does it likely correct from service feedback?
