512 pump gas build question.

I like the 440Source 512 package with the 7.1 rod and 17cc dish. Will give you 10.8 with the .039 Felpro gasket and zero deck or 11:1 at +.005". With a mild set of 78cc RPMs a similar combo went 600hp/600tq.
Otherwise you can enlarge the chambers a hair to lower it if you're running the short rod combos. Personally I wouldn't want static much higher than 11:1. Unless this is a max horsepower effort the extra .4-.5 static means nothing, and with that stroke it will not be "soft" down low.
