I'm currently rebuilding a 12A engine and was I intending to do an extend port, but I am now contemplating a half bridge or a full bridge. I’m wondering what are the advantages of each type of port.



The car is only driven on weekends and for participation in low level motorsport events.



Any comments?

make sure the porting your thinkin of doing is going to be legal for the racing your doing.
