Default 4 stroke valve sizes???

Anyone know any of the intake and exhaust valve sizes on the following engines?

honda gx25
honda gx35
briggs n stratton 34cc
ryobi 26cc

Whats the bore and stroke on the ryobi 26cc 4 strokes? I'm going to try and do some rc boat conversions with one of these motors. I just need to find out which one would have the most potential.

Jace,
Since the B&S 34cc has a flat head, it would be fairly easy to make a water cooled head. Here are some photos of other peoples aircraft conversions.
