Well finally got some new parts for the rs and been working on it a little.

Had the 16 valve had skimmed, removed the valvesprings so the springs from area-six can go in.
Been to the ford dealer to get some headbolts, cambolts, gaskets, oilseals etc.
Found some baily stuf on the net and bought a swirlpot, oil seperator tank and header tank

Also as i'll be using a rover inlet i made an adaptorplate to make it fit the zetec head.
