Haven't gotten that far yet. The engine is still on the stand.

I have purchased the Z-Story Street headers with full exhaust all the way back. Sean was easy to work with and the equipment is beautiful....however there were some serious issues with the headers that I received. He knows about the problems and hopefully is correcting for future orders. The flange needed to be ground down on each end to allow for the intake to fit and be bolted up. That was fairly straightforward and with some grinding on the flange edge I got the intake to seat nicely. The major issue is the the angle of the pipes coming off of the flange.  Several of the thick washers used to hold intake and exhaust in place had to have the edges ground a lot just to get them to slip onto the stud. I had to scrap the stud all together on the fist pipe and use a bolt with normal flat washer because the stud actually hit the header pipe before it would seat against the head. I am a probably a week away from getting the engine back in this car. I hope everything seals up OK but I have a feeling I will have to go a different route. A couple of the manifold nuts were VERY tricky to get a wrench on to tighten, impossible with and socket and swivels because they are just to close to the pipes to get any clearance for a socket to slip over the nuts. 

I was very excited about this exhaust system but I fear I have a lot of money tied up into a header I will have to replace. 

I've been told that recently, sorry to say. No low end torque. They're beatiful though. Zcardepot had some allen headed exhaust studs and I'm sure others do too.

THANK you!!! I was beginning to think that nobody got that at all!!     

I have the Spirit Garage system on my 240Z.  It is a thing of beauty, RHD Japan super easy to extract the cash out of me and it fits amazingly well...until you realize it was developed for a RHD 240Z when you go to connect your steering arm.  I had to "massage" 2 of the primaries and am not super happy with the result, it fits great but the clearance effort is not great.  I am going to have to take this to someone who can modify two of the primaries waaay better than I can.  One other point, this header is made for triple carbs as the profile for the primaries means you turn your SU heat shield into origami.  

I also have laying around in my garage one of the last, if not the last, header that Stahl built.  For all I had read and had known about Stahl headers I was very surprised to see it arrive with a thin flange that meant we had to have shims cut down to clamp it on properly.  It's a nice header but painful.  I really should get it out of there at some point.
