Should work, although they are not the same... the i has bigger ports. If it was my car, I would replace with an e gasket.

Shouldn't hurt any thing but it can cause some abnormal folw through the intake and head.

They are the same I'm fairly sure, or at least they only make the I gaskets now. I bought a 325e headgasket kit and it came with I gaskets.

if you use the i gasket on the e head with e intake you end up with a gap between the manifold and head causing a little back pressure in the intake. weather or not this effects performance i don't know. But in my testing it does change the way the air flows.
