Here i have a ported cylinder head for an st170 duratec engine. Low mileage head has been stripped cleaned snd ported,, as can be seen by the pictures the ports have been opened up, over standard, you will need to port match your inlet when fitting for best results, i have the same head on my escort with matched omex inlet and 48 mm throttle bodies. This head will be built back up with valves and new stem seals, original cams with both pullies and the vvt controller fitted and a fresh skim so it will be ready to fit to your engine.
