Will 95+ vented opti fit a '94 non-vented opti setup

Are there any modifications that need to be made to do this?

To do this you will need the 95+ timing cover, 95+ timing chain, longer dowel pin in the cam, and the 2 vacuum lines. IMO, it's not worth doing unless your doing a cam swap.

Not only a longer dowel pin, but another cam..
The 93-4 cam does not have the 'nose drilling' that the vented opti requires..
