I think everyone agrees that the 37 head is a better design than the early low comp head and if fitted to an engine in good order will prove beneficial. My comments on plug fouling were based on my own experience of fitting the 37 head to unknown worn engines, which generally are better using the early head.
I have a couple of the angled early heads and have found these to be very good, I had one on my old Supersports type special in which I had the pleasure of out-dragging a blown MG away from a control in a VSCC Measham night rally. Nowadays I am a firm advocate of the Ricardo head as made by Dave Dye. I recently put one on my 31 saloon in place of a bronze Ulster head and the difference in smooth running and power is noticeable.
