    you need to talk to a engine designer and or builder, if you mention what youre wanting to achieve they'll asist you! theres other ways of accomplishing compression without milling the deck.

    I would deck the heads before touching the block. A stock l33 piston is gunna stick out of the hole around 0.006. If you knock off 0.020 that only leaves you with .0.025 between the piston and head with a 0.051 gasket.

    Ya maybe I went to the wrong machine shop but he told me to research if it was possible or not. Lol he hasn't seen the block yet to measure. If I did the heads .020 off would that cuase intske alignment issues or valve clearance issues? I read where somebody did that much on a ls6 but I think the ls6 has dished pistons.

    You can go up to 0.035 off the heads without alignment issues and as always you should check PTV. But that cam wont have any issues with clearance!
