There are pistons out there that will do what you want. You just need a little longer distance from the wrist pin to the top. I thought Mitch or somebody listed different piston heights on here once before. Find a WD45 piston and measure it. Figure out what you want for Comp ratio and what it will take to get that, then shop for the pistons.

i posted a pic of a leroi rod it should be in the archives . the 8 inch rod has a canted cap and was only used in the leroi 226 engines that had a combustion chamber in the head . you can also turn the crank down to a h rod journal for thier rod was 8 inches long and are a little more easier to find since farmall hs were plentiful . another option is the c farmall rod it has a 1 3/4 journal and is 7 1/4 long . You can gain 1/2 inch of stroke for a gain in cubic inches without a comp ratio change from factory and utilize the factory allis pistons once the c rod small end has been opened up.
