Thank you for your response;
TOP LEFT:
The BM heads use an 8mm stud to mount head, these holes are either ¼” or for 6mm.(.260”)
Also the overall width of this head is 4&7/8” diameter, smaller than the BM heads.
The spark plug hole looks like it’s for long reach B9ES or N-2.
Top of the plughole to the deck is 1.300”.
CTC mount holes are 1.313” approx.
Weighs 1-pound 1.55ozs
The Reed Engineering head has a 2.083" diameter going into cylinder.
