I have a 351 Cleveland 4V and I ordered an Edelbrock airgap intake from Summit and they told me that the airgap works with both the 4v and the 2v. When I got it I noticed that the ports are smaller than the head ports. I'm wondering if that's how they are, or if they make one for 4V heads.

 

im not sure but i wouldve gotten one part specific only

 

if you use that intake you'll be choking your heads down to 2v size basically. hell you'd have a better bottom end but i would send that damn thing back if it were me.
