They look stock to me. Look at all of tha casting slag. I can't see the top of the exhaust. What to the bottom's look like. I have some ported #'s for you. These are all close. Exhaust 34.93 mm Intake 55.55mm Side 54.06 Sorry do not have a stock 1200 cylinder to measure.

That is the snow mobile piston in there.

so its just a stock cylinder bored out to hold the snowmobile pistons?
do u have to run different heads with these?

yes you need to run diffrent heads. the dome angle on the snow piston is different than the pwc. pwc is 9 degrees and the snow is 11 degrees.
i know where you can buy the right heads!
lets see some pics of the bottom of the cylinder and cases. looks like there is no porting done to those cylinders to me.
P.S. what are you doing with the pipes in that boat? I know Del would love to buy them if you are not going to run them.
