Take the head gasket off the motor, replace rings from pistons...

I've got a rough idea but I wanted to take the head gasket off the motor…. but I wish there was like an actual guide I could follow…. I went in blind changing the transmission oil… that was as mechanical as i can get…. but seeing as the guts of the beast will be exposed I suppose alittle shaving off the head to get a higher combustion therfore more power out of the little 6 cylinder thats wants to be an M3 when it grows up?
