Re: possible piston combinations
Im not certain about other piston combinations but I'm sure it will not be hard to get pistons with the correct compression ratio for your needs from an engine shop. If you plan to boost it then you will need to look at a lower compression ratio than your NA and you will need to know what sort of boost pressures you plan to run so you can get suitable pistons.
You are certainly not offending anyone with your questions and welcome to the forums.
