If you read the sticky post about the 2.3 lima, you will find that the changes were to the valve stem diameter, but not much else. Later engines had a combustion chamber change, again, from the sticky.
The sticky is the first post in this forum. This is where it lives:

From what I have read, the cam and roller followers can be installed into a non-roller head without problems. I'd consider doing it, but have only seen one listing on c-list for a cam & followers and it was quickly pulled by the poster.(dunno why)
Oh, I can't answer the question you posted. I do not think it matters. If you have a cam & followers that fit the valve stem diameter, it should work.
