I would pick up a set of Cometic .027 gaskets or even consider going with the steel shim gaskets at .021 with the piston .027 in the hole either would give you effective quench especially the .021 which would put you @ .038 which is about ideal but I'm not a fan of steel gaskets with aluminum heads... The MLS would put you @ .044 which is near the top of where I'd like to see the #... .056 is just wrong, either less than .050 preferably less than .040 or plan on lowering the compression & timing quite a bit....
