Fuel Injected vs Early 429 - 460 intakes

I am in the process of developing a Megasquirt FI system for my '80 Mustang with a 429. I have opportunity to acquire an '89 Multi-port 460 intake manifold-complete. If this would fit It would eliminate a lot of work.
My heads are early 70's (D??? - something). I have been told that the FI heads are different and the manifold will not fit. When I look at Blue Thunder and other places I find no differentiation (except CJ - Boss).
Does anyone have any input - advice?
THANX

The intake and exhaust ports on the fuelie heads / intake have been raised a bunch vs the earlier versions. The intake is not compatable with the passenger car heads with out mods.

You will need to convert a victor to efi. The stock fuelie intake does not flow worth a tinkers damn.

the lower efi intake LOOKS like it would flow pretty well. Is that not the case? Is it just the upper that doesn't flow well? EDIT: When I say that it looks like it would be a decent intake, I mean that it appears to me that it's about equal to a Performer intake. The runners look to be maybe slightly larger than a performer, but certainly not a Stealth or Performer RPM.

Only reason to use that intake is that it is set up for injection, but as said is not a bolt up for early heads. In this case be better to convert a Torker II, Victor, TFS, or tunnel ram. For a DOVE/D3VE head I'd go with the TFS intake, drill it, and add the injector bungs.

Tunnel ram can be a neat option if you have a CJ port head, and a more serious engine, but runners are really steep for adding the injector bungs - ask me how I know :roll:

Older vs Fuel Injection Heads

Thanx for the good info
Flow characteristics etc aside - what would happen when I dropped a FI Manifold between the D2VE heads on my 429 ?
If I knew what the mods to make it fit would be I may want to go that route instead of the bungs - Fuel Rail etc would work = easy
I am not looking for ultimate performance only drivability.

DO NOT USE D2VE HEADS. ANY heads are better than those, whether they are D3VEs, D0VEs (what I have) or fuelie heads.
If they have big round open chambers, DON'T USE THEM. I learned the hard way. They suck. other people will fill you in.
