The Courier 2.3L Lima is the same. There is no difference on the exhaust side of the 2.3L heads. Some may have holes for the AIR system. This includes the boat and industrial engines.
The intakes varried thru the years with the oval, D shape, round port and in the 90's they went to the DIS style engines, with an equal spaces D port intake. No distributors.
The D port intake can be used on the oval port head. years are not spot on, however close. Oval port 74 - 80, D port is 81 thru 94. The 81-83 Round port manifold is all by itself as is the 95 and later DIS engines.
There is a lot of accurate tech info on www.powerbyace.com
