So, this amounts to a low compression (for then) base small journal 327.

Unless the heads originally had 2.02" x 1.60" valves and screw in studs/guide plates, they're not from a 302. Head castings like the 461, 462, 291, 186, etc. were used in 1.94" x 1.50" valve size (w/o plates and screw in studs) as well as 2.02 x 1.60" valve sizes...
