Polaris high performance head

[dony409]

I have a 97 rmk 700 and when I bought the sled it has a new motor and Thea parts one but the guy had two heads one purple one red he said he thought one was a high performance head but didn't know which one and there is not part number on the red one either

purple is the original 97 head and the red is what came on them later. the 97 head is suppose to be better but I've never measured the cc or the squish.

Hmm I wonder why that would be on the original motor? The guy before me put a big bore kit in the new motor... Waste of money our other 97 rmk has reeds and a pipe and wraps circles arond t lol
