anyone know if skyhawk cylinder is diff from normal?

getting ready to stock shelves with high-hole pistons for skyhawks, but haven't measured cylinder to see if those have diff heights or diff port timing from the low-hole piston cylinders

anyone know if I need more cylinders to match them or not

given up on finding answer - seem about 6 diff conrods that also make port timing different

I'll just stick with the old way which seems most cost efficient, of opening a new kit, taking off cyl or piston or whatever, sell that part & put whole rest of kit on shelves as repair parts.

measuring would be my preferred method (even absent any factory part # markings on cyl), but some dead cyls here on the aluminum recycle heap are of unknown origin & I just don't feel like ordering a motor from every guy on ebay that has one just to measure them all

add to that, the fact that when some guy walks in with a dead, unmarked, motor it becomes a real problem figuring out what he needs (tho usually, they leave the motor home & just want a part that fits)

my own motors have changed in last few months & I didn't know it till I had to open one and fit a part to it (that turned out to be wrong)

I have some pistons and cyls coming in that I will measure to see if they work at least on what I have here.
