i can post some pics up of my head but remember its a shonky silver top lol
no seriously if you want some pics i will send in a pm
cheers paul
i have loads of pic's of proper ported zetec heads was just interested if anyone had done a bit them selfes and had pic's.
i have spent a lot to time researching head porting on turbo engines and been taught a fair bit by a top head man so this wont be a shit job by a long way .
and i have ported the the first set of ports and made a mould to match the rest so they will all be the same.
only time will tell if i make more power but im sure i will infact im sure i will max out the turbo
