Re: head cc's
your best bet is to measure it mate
if i told you 60cc for example
and you went off that info, and lets just say you had a turbo
and worked out off my info that you had 8:1 compression
then ran a lot of boost thru it and melted ya pistons
cos your comp ratio was actually 9.5:1, cos i gave you the wrong info
chances are your prob not gonna be very happy with me lol
if you measure them, then you know for sure what cc they are
i could tell you 60cc, and if the head has been machined in the past
well then thats gonna be the wrong info
