    260 Heads

    What is a stock CC of a 260 head. I just removed a set of 260 heads off a powerhead and they looked Tight. I CC them and they came in at 26CC i am thinking they have been shaved a lot,my thoughts are they should run along the same as i normally run 34/35CC on other 2.5s. Thank you for the help.

    That’s correct... 26cc come on the drag. We run 21cc on our motor. I think stock are around 37cc or so?

    Stock Heads are 38cc's They also made some 42 cc's on a few fishing motors. But The majority of stock heads are 38cc's.
