ok fellas this might sound like a stupid question.....but.....i have a 4agze in pieces. its a coilpack and cas model, its also the AFM type.
now the ports look pretty big but i am wondering how i tell for sure if its big port or small port.....i know i may sound like a total tool!!!!!!
im wanting to know cause i want to put the NA cams in my head to increase lift and duration (if its the head with small port cams) i looked round using the search tool but couldnt work out how to tell big and small port. also im going to port the head....but thats not really relevant.
can i tell by looking at my head what sort it is.....
sorry if this sounds bit dumb!!!
