Gentlemen I have a question. Years ago I started tearing apart my first Corvette a 1984 4+3 Doug Nash car. Mine intention was the put a LS1 with a six speed In it but years went by and the car has sat apart and I have acquired plenty of fast Corvettes since then. Well my attention is back on the car and I'm pulling it out of storage. But my interest isn't in A LS swap anymore. I do want to go back with the original engine because it's my first Corvette and I have a lot of fond memories of it. That being said the engine isn't exactly stock I had put a cam in it years ago. And heavily ported the intake and install long tube headers. I intend to rebuild the engine and me being me I tend to overdo things. So I was wondering what Heads can I use to replace the original 84 smog Heads. I've heard that 86 aluminum heads off of a two Tuneport has the perimeter bolts like L83 has. I'm just looking for a factory aluminum head to replace the 84 heads and everything will bolt up and line up correctly

As always thank you gentlemen

I did a build up of my 84 Xfire b4 buying the ZR. It involves quite a bit more than some bolt ons. My Xfire ran 13.3s @ 104.6mph on street tires and 3.07 gears. I used TFS 23D heads.
Be glad to collaborate.
