340 stroker cam

So if I boost compression with a piston change from dish to flat top I can increase compression to 11.8 then go with a smaller camshaft?
Current engine, .030-360, zero deck flat tops, Trick flows, .027 X 4.04 head gasket , 11.6-1, HR224@050, 93 octane, will tune it up more later and see what’s what.
