Yes they both have 4 inch bores but if the chamber size where the valves is different it will change the compression.
Answer If you are checking # on a Chevy head they are under the valve covers in the rocker vally close to the center of the head . the # there can tell you when they were made and for what size engine and also the size of the ignition chamber also a good idea of of the size of the valves installed at the factory .they are cast into the side of the cylinder head,as the name may suggest

no the inside of the head will be a different size
The combustion chamber size of 305 heads, specifically referring to the small-block Chevy 305 V8 engine, typically measures around 58 to 64 cc (cubic centimeters). This size can vary slightly depending on the specific model and year of the cylinder head. These heads are commonly used in applications where lower compression ratios are desired.
No the head gaskets are dependent on bore size
