high compression egge pistons for 273

I just built a 273, i installed J E pistons, dome hgt is .275, piston flat sits .046 below thedeck. 360 head, @ 66 cc, felpro 8553 gasket, C R is 9.28. i've never had to retorque my head gaskets on my 340 or 273, i use moly lube on bolts, 340 is at 80#, 273 is at 85 #. just food for thought
