Why don't you build it and find out.
A stock un modified 305 head will really limit the power.
If you want the 305 to work and the cam to work the heads need to flow
Either fully port or replace. 1.94x 1.50 best.
You got to be willing to work the heads.
You are right and I'm not going to type out 30 years of experience.
The cr matters. But 10:1 is too high for a boat motor.
but just right for the street and critical.
Not a bad fun lil 305 motor for a Camaro or Malibu or light street rod. 330 ish HP. maybe more.
remember, likes gear and a converter.
built 305's need to rev up. the gears and converter make it fun and spunky on the street.
Here is a .040" over 305 10:1 plan I'd be tempted to add a 1.6 rocker to the intake side with that cam and ported heads.
Cleaned up vortecs shaved to 58cc and a RPM intake would rock on this 305.
