How come there are many new high compression heads and piston sets made with square intake porting but not enough 12mm or 14mm short or tall square intakes made most of the originals made were round ports and you can't find gaskets for them. Anybody have an idea I have check most of the moped dealers on line all they have is round port gaskets unless you buy a hop up kit then you get the square gasket to match the head but know your back to square one and stuck with the original round port intake weather you have a tall 14mm or short 12mm that really sucks.
