Are your heads the 440 intake port size or the M.W. intake port size? If M.W. size and you try to use the Eddy RPM inatke you will have a massive port misalignment issue as well as possibly a massive vacume leak where the intake doesn't cover the head intake port size work shruggy scope The ones I have are M..W. port size so I had to use a Indy intake with matching intake port runner size shruggy
