Does anyone here know 100% sure if the warrior head will work on the big bear? I've heard that the bore is the same it's just the stroke thats different, So theoretically the head should work. But I've heard other guys saying the bolts wouldnt line up in the cylinder to put a big bear cylinder on a warrior, if thats the case the holes in the head won't work either. Reason I'm asking is I have a Big Bear with absolutely nothing wrong with it and a half dozen warrior heads laying around, and I was considering ordering a cam and oversize valves and a spring kit then porting and polishing a warrior head then just stick it on some saturday. That would eliminate down time to rebuild the head off the big bear, but i would be severely aggrevated if I went through all that and it didnt work.
