Awww crud - mystery heads, can anyone help identify these? Options

So I pulled the turbo intake and single Weber off the red car yesterday, that was discussed here Removing turbo set up

I went to put the dual Weber’s back on and there is no way it will bolt up. The bolt holes and spacing don’t line up. Looks like the heads on there have a significantly larger intake port and bolt spacing is different.

Blue is what I took off.

Red is standard 2.0 intake.

First of all - you guys are awesome.

It's always been temperamental - shocker - to a point where it is a pain to live with. Love-love-love the suspension and brakes (all 911 stuff) so I think I am going to pull it out and put a 2.0 in for now.

Eventually this will get the 3.2 when I'm ready for that.

Once this thing is out I may fool around with getting the intake set up for regular induction after I get a better sense of what the hell it is.

Thanks for all the responses - hope everyone has had a good Sunday so far.

From the looks of it, someone put some work into this motor to make it work with a turbo.

Chances are, regular induction won't work well on it.

Good morning guys.

@SirAndy - I think you were right. Your, any other guys, observations here had me do something that seems obvious in hindsight. I spent a little bit more time staring at it, with the benefit of having taking it apart, and the mixture from the carb goes through the turbo before it gets to the head. Meaning-there’s no way to bypass the turbo with all the plumbing is set up, so no wonder it was grumpy with the boost dialed out.

It looks to me like this was set up to run hard for relatively short time intervals.

I’m super curious to see what this all looks like when I get it out of the car in the tens off.
