Depends on the head, but I think there is information about this in a post by kenny S...pretty sure he posted in the sticky about the Lima engines above so have a look at that first...otherwise search for Kenny S and check the links in his post...

EDIT: Sorry, it is Kenneth S and I found this link...

And, more specifically...

There are several variations on the 2.3 heads though they break down into 4 distinct types:
1. Passenger car oval port heads-’74-’80 Mustang, Pinto, Fairmont, Bobcat, etc.
2. Passenger carD-port head-1981-’90 T-bird, Mustang, Etc.
3. Truck round port- ’83-’88 carburated Ranger
4. Dual plug D-port- 1989-’01 Ranger. The '89-'94's and '95-'01's have different combustion chambers and ports.
