Don't build a engine without the gaskets!! It's just bad business!
I would suggest that you keep the base gasket & go with a thinner head gasket if you want to raise the compression. (Thats only if you're sure you have the piston/ head clearance!)
If you really wanna go crazy... do what Baird did & smooth & match all the inside transfer ports & port match the intake & exaust, & also smooth the inside of the carb. (But keep the gaskets!)
