Facts: - no O-ring groove (this always breaks on the original head) - Toroidal combustion chamber - Compression volume is 26.6ml at 1.3mm squish clearance -> This is a compression of 12.5:1 (Idea: same compression as BFA head, but with 1.3mm squish clearance instead of the BFA's 1.8mm squish clearance) - Fins slightly flatter than original (Idea: save space, lower-sitting cowl possible) - Omega combustion chamber for faster combustion - Additional cutouts at the cylinder bolt positions to allow the cylinder and head to be removed together
