So, I've decided on making a start on this which will probably take way longer than anticipated!

With regards to the head, will the standard cams/head do? Apart from the valve springs of course.

I've seen a few different 2.0 heads, off focus's, cougars, mondeos (all blacktop) - would there be any difference in purchasing one off any of the cars above.

With regards to the mileage, should I be concerned with 70 - 80k milers? or buy mint new one?

I will have move questions as this slowly progresses.

Cheers
