Yes GMDad the other heas will bolt up. But you may run into a issue or two with mounting what came on the other.Some bracket holes may not match up.
That is why I am thinking of the mount kit from E.C.I. Stock is OK but I have never seen so many vacuum lines under one hood at one time in my life and it has a fairly large catalytic converter right at the exhaust manifold along with the smog pump, etc.
