I'm going to get one of the complete 2.3 blocks from Burton Power. I'm guessing all I need on top of that is a 2.0 head, water pump, oil pump and cams.

At the moment I'm running a 2.0 195bhp zetec but I'm looking for a bit more torque and the weight saving so I'll probably get the cosworth 200/220 cams which run the standard springs.

At this level of tune is there any point getting the head ported and polished? Also will any 2.0 head do or is the fiesta st150 head better for any reason?

any advice welcome
