I have taken off my head to replace it with a high compression head. While I had everything apart I changed all gaskets and my piston rings. Is there any certain position they need to be in when putting the cylinder body back on

garrett.4:
If the engine is a 2-stroke, the piston rings should be pinned so they can't rotate and catch an edge on the ports from the ring gap.
With four strokes, I usually just offset the ring gaps depending if it's a two, or three ring piston.
Keep in mind though - I don't claim to be a pro - just a tinkerer.

It is a 2 stroke. What do u mean pinned so they don't rotate?

The ring end pins face the intake.
It's that simple.
Of course the ring ends have to be around the pins......

There are 2 pins in the piston on the intake side about 8 degrees or so off to each side.
The gap in your rings needs to match them to seat.
