I am looking for options for 12:1 pistons with out decking the head on a bored 5.3. Plan is 12.5 static compression ratio with a 3.898 bore. I am using the sns stage 3 cam, but I was really interested in the wiseco pro series pistons, but they don't seem to be available in a comp. that high that I saw. I am open to other ideas though, would like to be able to get something off the shelf though, with a steel top ring and a decent skirt coating that will handle some spray down the road if I decide to add later.

It would help if you mentioned what heads you want to use.

Did you see the PN K447X3903? The 12cc dome on them should do it depending on the heads you run and how big the chambers are.

Sorry, I will be running the stock l33 heads hitch I believe are 61cc. I would like to get 12:1 with just pistons, and then deck the head to fine tune to right about 12.5 compression. I am looking for right around 9:1 dynamic comp.
