I think if it was me I'd drop the compression down and forget quench. Otherwise it's spending a ton of money to verify and machine everything to be dead on to keep the distance right. I think 10.5:1 with those heads wil be harder to do with those pistons. You can get 10.3 easy with zero deck flat tops, a 68cc chamber, and the thin MP head gaskets. Plus no worrys about stroke correction, indexing, milling domes, or equalizing the chamber depths to get some quench with your 10.5:1. Also, the cam is a decent size for a hydraulic, but not huge. Is it a fast rate deal that is supposed to build pressure? I am concerned that any higher than 10:1 is flirting with ping issues with those heads and the 3.58 stroke. I could probably tune out at 10.3. Might be a lot harder at 10.5:1.
