The inlet should, not so sure about the rocker cover tho. There's two types, early and late. What year is the corrado that the rocker is coming off of?
I think thats gonna be the earlier one then. The inlet manifolds are all the same, the rockers im not sure on though.
This may give guidance... http://www.clubgti.com/forum/showthread.php?t=221231 Mk3 inlet manifold is different to a mk2 KR item too iirc
