Was wondering what u would gain by swapping to 470 aircraft pistons or a dome piston with higher compression. ..rpm , hp?
 
I'm not sure but my buddy has some 10:1 pistons for sale cheap and his motor ran excellent with them.

Superior sells the rings , they are not any more expensive than other aircraft rings. I have the ones for sale in the classifieds pm me for bargain price if you want them.
