I just polished mine, enough to make them smooth and get the rough casting out

No need to polish the intake side, but the exhaust is fine.

It is not all about how big you can get the ports, but the shape is very important.

Taking out "meat" at the right areas...

just get a gasket and match the ports to it. Fix the short turn radius so it's smooth. (no sharp edges)

Gasket are not porting templates. They are just for sealing
