Factory OEM Cylinders Polished 65.50mm Bores *USED*
These will need to be bored. Slight port work. 
Pro Design Coolhead studs already installed. 
Came off 4 mil engine that had spacer plate. Would recommend having a nice port job done on them.

We can also get new pistons for these cylinders. 

We can bore them to what piston size you would like. Cost to bore is $90 per cylinder.
