Like the title says, will the dirtbike head work on the 4-wheeler? If so, what kinds of performances changes could be expected?

i have done it. had a full blown out pro circuit head on it. and did not like it at all. didnt rev fast enough and felt sluggish. the intake ports are actually smaller then the quads
