Great job pushing through it all!
After seeing how my idle mixture was affected when I installed these headers on my car I called a few clients to see if this was an isolated event. Every one had to bump the mixture rich. I am going to include this observation in future instruction sheets.
The headers do have a few unexpected characteristics. Another is they are more quiet than the stock heat exchangers at idle. I was very surprised at that. There is a cammy sound but it is very smooth and crisp, not at all unpleasant. You can tell there is definitely something extra having short tuned equal length primaries and secondaries.

I got the chance to take the car out again today and I really am enjoying the exhaust. I'm surprised how different the car feels. By surprised I mean because I had the good 86-up (Euro) heat exchangers and a simple 3" magnaflow hanging off the turbo, I kind of wondered whether or not headers/exhaust was my next logical step in terms of mods to the car. I hear SC cams, and shorter ring and pinion really wake these cars up too. So anyway, there is a huge difference from my old setup to this one. The sound is great popping away at idle, and it sounds like a flat-six should when I'm on it. No drone. I never was stoked about the magnaflow note; it was a deeper tone that never sounded pissed. And boost is definitely building around 3-400 RPM sooner. I can barely keep from snickering when I get on it. The dual outlets look all-business, too. It's also much lighter, and I took the rubber blocks off the car while I was at it and like that look (and weight savings) too. All in all it really has added to the drive.

It's also like 21 degrees here in NY, and so of course it's pulling even harder from all the good air. Cold tires, cold road, cold air and bang! the thing kicks sideways around 4500 as the tires break loose in first.

Oh and one more thing, did I mention it was cold??? I'm highly interested in the estimated availability date of the heat boxes.

Glad you like it! Yes it is cold here as well (relative term I know). The heat exchangers are with the metal bender right now and I should have a set to test next week. Once they get the big check mark it's off to production.

For the header install, did you have to backdate your oil lines for proper fit? It is necessary on most aftermarket heat exchanger installs GHL, B&B, etc.

The headers were designed to accommodate the early oil line and turbo oil tank. Ken has the later line which is a little close. You can always option to use the '78/9 USA "back date" oil lines to completely remove them from header proximity.
