According to Mortec, the 14022601 heads are 1.84"/1.5" with 58cc chambers.

I'd assume the 624 heads flow more air. Has your block been decked? If not, have it decked so that the pistons are 0.025"-0.030" below deck height, and use a 0.015" shim-style gasket. This should give you close to 9:1 with the 76cc heads. And port dem sum*****es.
