Those have the same compression height as mine. In fact, I still have the brand new set I mocked up first in the block. They set up the same at .007" below the deck. The only difference is, the 1292 has a dish and my current pistons are flat tops with one long valve relief. You'll need to cut more than .024 to get zero deck. They'll probably sit similar to mine at "around" .060 in the hole. Still a lot better than stock. How would I know if you're missing anything? What are you supposed to be missing?
