When they do B20 engines and swap them into our car they usually keep GSR block and use the B20 head right?

Does this setup retain piston oil squirters that are in B18C1 engine?

Also is the main reason for doing this just increased displacement and how does it alter the compression ratio compared to a factory GSR head and block ?

Seems like scarifice alot building a B20 B16 hybrid or whatever they call them. Oil squirters are something I would want. Not being able to rev as high seems like another big drawback.
How much more displacement do get out of B20 B18 hyrbid block?
Is the stroke longer or just mainly the fact the bore is bigger ?
Couldn't just take a B18 and bore it out or put a stroker kit on it and achieve the same thing?
Also are the B20 hyrbids not lasting as long because they do not have oil cooler and or squirters?
