Larry,
Funny you should bring up that particular combo- when the original '77
engine threw the #3 rod back in '88 I ended up with a 1500 engine from a '73
Midget. Kept the head from the '77 so it would have the correct air rail
ports and the unleaded valve seats. Just had it surfaced on the advice of
the shop that I bought the '73 engine from in case of warpage or difference
in the mating surfaces between engines that had run in. No problems at all
in my case, although you're going in the opposite direction from mine. The
'77 head will have the air ports to be plugged if you don't have the later
smog setup.

Hi all,
I pulled my '73 Spifire motor and have it ready for the machine shop. The
head has a tapped and plugged hole right above the rear stud for the
intake/exhaust manifolds.
My'77 motor head doesn't have this plug and my spare, unknown year head
doesn't have it.
Are the 1500 heads and blocks interchangable?
