OK
What year did they switch from Cast Iron to Aluminum?
...like '90/'91 right?
Are 2000/2001 a good performance upgrade for a '93?
...or I could reuse my ported '89. But even ported, I'm not feeling performance gains.

What I'm thinking is, when I nab that 2000 intake, I could grab the head too.
Plus I'm going to get a performance exhaust manifold ~ 2.25"/2.5" all the way - no cat.

Just thinking out loud
