The biggest problem is the flanges are too thick for the early car, you ll need longer studs on the exhaust side and that work tends to be expensive because the old studs do not remove easily.
The later exhaust has inserts that fit into the head so the gaskets dont blow. The inserts in the exhaust pipes need to be removed or ground down so you can flush to the head.
You could do better.
