Could it be a racing head? Pic might help. (and include the stud hole dimensions, it may fit another engine).

The 125(s) have a tipped spark plug (generally) some racing heads have a second plug hole maybe used for pressure relief valve.

I recently aquired a cylinder head that was supposed to be a 125 and it is more round than egg shaped. The 48 - 53 heads are egg shaped pt#16652-47-53. Any body got any info on this round head?
