I was just wondering if anyone knows of any dome pistons or larger rings?

The size of rings are dictated by the machined grooves in the pistons and the bore they fit, but if this answers the other part of your question, pistons with a higher compression ratios are certainly available. Higher displacement jugs as well. All it takes is money and desire.

this link is to a old thread discussing the pistons available at the time http://www.bonnevilleamerica.com/forums/...rt=all&vc=1
the differences are pretty obvious. the after market pistons are forged and the stock one cast.
