Super H

I had to take the head off my Super H cause it was smoking like a freight train.It still held really good oil pressure, and run good. When I got the head off, I noticed you can take the top of the pistons and move them back and fourth, more than I think you should be able to; now aren't you supposed to be able to move them back and fourth a little, right? There's no ring travel in the sleeves. There's was no antifreeze in the oil. Does it need a set of rings? I'm new at doing any of this, so any suggestions would be gladly appreciated. Thanks in advance.

Smoking can be an indication of worn rings, but you should have done a compression check before removing the head. Yes, the pistons can move, but how much? There are specs for piston side wear, like everything else. Also out of round and top to bottom wear, front to back and side to side. Good time to practice micrometer measurements. New sleeves and pistons solves it all. Good oil pressure would indicate that your bearing clearances are good, mains, rods, cam- along with oil pump capacity.

How about checking the valve guides for wear; excessive valve-to-guide clearance will cause a lot of smoking & oil consumption.
Is the drain back hole in the head open so oil is not pooling in the head?
