305 heads for my 307 small block chevy

Hi friends,

my name is Alex and i am new in this forum which i think is extremely useful.

I have a SBC 307 (casting 3970024) with stardard cam, flat pistons and heads (heads casting #3927185), running with a new 670 Holley Street Avenger 4bbl carb, Edelbrock performer plane dual, headers, new HEI distributor 65.000 volt internal coil, Accel 8.8 mm spark cables

I just bought a comp cams kit K12-238-2 to install it cam p/n CL12-238-2 but i have not installed it yet, what do you think? Comp cams recommended this size of cam for the size of the 307 cubes.

What would be the best 305 heads for my 307 if i really want to rise the compression ratio of my 307?

DoubleVision and MachineShop recommended a set of 416 casting 305 heads at 61ccs and have 1.84" intake valves

I really need help...oh by the way i live in Santiago, Chile, and i doubt there could be here a good pair of 305 heads
