I run a Fel Pro Performance Z1215...It is the one recommended for the Eddy's along with their Performer intake...four composite gaskets and aluminum valley pan..if they milled the heads to reduce the cc's in the combustion chamber it will drop the bolt holes in the heads for the intake manifold...this may cause you alignment issues...if they milled the deck of the motor same effect...
