As a few of you may already know (due to my MANY questions already) I'm doing a 4.0 head swap. I got 4.0 headers off of eBay and a 4.0 HO head casting no. 7120. Is the intake for the 1980 258 different thatn the others? I'm haveing a lot of trouble getting the thing to fit and it doesn't look like any of the other intakes I've seen on the online writeups. For one, when one lines the intake up with the dowels on the head, intake ports are left wide open. I pulled the dowels out with a puller but the seats for the mounting bolts are about 2 inches away from the head, whereas the seats for the headers are 0.5". Do I need one of the later aluminum intake manifolds to make this work?
Here's the dowlels. See how they don't line up?
This is the best fit I can get.
Here's the seats for the bolts I was talking about.
