Many of the OS 77's were designed for the Byron Fan and came with a large head. If you have a small head you can use it in a dynamax fan or equiv. That being said, the 77 has a propensity to shell the con rod. Probably because the con-rod clearance is too small and not .004 like the OS 91. There was a co. who made a living on making replacement conrods, I believe it is performance specialties. The OS 91 is a beast in comparison. Is that too much info.
