You shouldve searched first, but since my post number is low, ill help ya out.

None. THey both are identical, except the EFI has block off plate on where the fuel pump would be on carburated heads.

I prolly searched wrong again..... :smokin:
But I was under the impression that the cams or valves were different for the efi.

Reason for asking; I found a used head for cheap and thought I could use it for a spare since mine is make some unkown noise. :nuke:

We never received the EFI model, but I read with interest a post on ORC about this. Seems the EFI cam is of a higher profile and when matched with 1.3 A rocker arms it gives a huge boost in bottom end plus right through. The EFI arms are a lot shorter, while the A arms are of course, much longer. So with the higher lift cam and longer arms, Cooter reckons he keeps breaking the Dodge motor mounts.
