so would a megane engine fit in valver,coz ive herd its just the block(bottom end) thtat will fit to a valver cylinder head,(and going from 1.8 to 2.0 would the valves in 2.0 b bigger?
 
the Megane bottom end fits yeah, the head however is different and wont match the fannimold iirc, so is therefore useless... unless of course your using ITB's. the Megane and Williams bottom ends are identical bar the rear strengthening veins on the Williams and the different location of the dip stick, but generally I'd say your better with a Megane bottom end as it's A) newer and B) will almost certainly have lower miles (in most cases). I paid £500 for a Megane engine on 24k the other year... bargain. Valver and Williams head will also fit any F7 bottom end, but the Willy head has bigger valves, so is slightly better for power.
