im sending my head to carpenter next week to be ported but as ive been reading bob recommends 425 to 445 cams for his heads. i have a gen1 1507 with web 395/378 cams as this is a daily ridden streetbike. my concern is that if bob ports his heads for those size cams then will my little cams be to small for his ports. i know very little about this stuff but ive read about air velocity wich leads me to believe that big ports and small cams equals very slow moving air that equates to no power gains. i know bob does great work so im hoping im heading in the right direction but if not please help me to figure out what to do. if i need a diff head porter than who can or should i use. thank you
