MMAD Porting - race port vs dune port - YFZ Central I have decided that I am most likely going to have MMAD do some re port work on my head Its currently ported by my local builder but I'm pretty certain Geoff can't get some more flow HP out of it I gave him a call the other day, great guy to talk to but now I'm confused on what to do What style porting do you guys have and what do you like
