Interesting, I didn't get header bolts or gaskets.  I spent a decent amount of time test fitting them to ensure that all the bolts started easily in the heads.  Some were really tough to get started straight, so I had to use a chain saw file to slot some of the holes a bit.  But I do agree that they fit my canton R/R pan without issue.

I'm also curious if anyone has test fitted them to an Indy Sr head ?

The dipstick on my M12 had already been bent and modified when I got the car from a previous header install.   It was no big deal to cut and re-weld it at the fitting to make it clear.  Hopefully, like they advertise, these will be the last set of headers I'll buy.

I'm also using the Canton RR pan. Fit is great there, lots of clearance! Thumbs Up

They didn't arrive ahead of the ETA? Timing was great though, no issues there. I did consider grinding on the crossmember but it's all nicely powdercoated so I didn't want to mess that up. I also considered shimming up the trans mount but the angles are perfect now and there is not much room in the tunnel to move it up much more.  I currently have the tunnel all cut out above the T56  to get it up high enough.

 Not really thrilled about it but I did have to hammer on # 2 cylinder pipe as it was touching the crossmember. ( brand new motor mounts installed)I couldn't start all the bolts as it needed to go back some as it was touching the crossmember. Can't see it when it's bolted up. I did email ARH before I got out the hammer, but got no response. It's not the end of the world, it won't effect performance but at this price point  hammer fitting shouldn't have been required IMO. 
They forgot one of the collector extensions and to ARH credit they did very quickly send me one but living in Canada UPS nailed me another $42 in brokerage fee's for a warrantee item, bringing up UPS total brokerage fee's to almost $450. Strong dislike for UPS! Unfortunately UPS was the only way ARH would send them.    I did put a straightedge across the flanges and they are not flat by 1/8" or so at the ends, but I'm hopeful the bolts will pull them flat  and they will seal. 
I was pleasantly surprised to see ARH included gaskets and header bolts. I didn't expect that. I did have to order 1" long header bolts as the ones ARH supplied were only 3/4" which was too short. Not a big deal as I had ordered header bolts anyway as I didn't expect them in the deal. 
They do look really nice! Ground clearance is great! Nice and flat/level with the oil pan.

A year later, I finally got around to test fittting the ARH headers and exhaust.  69 AMX 390/auto, with the BW M-12 and Canton pan.   I had to modify the tranny dipstick pretty heavily, the headers are tight.













This is still test fitting.   All the clamps are loose.  I did have to shorten the pipes between the header and X-pipe, as they didn't align correctly with the header collector.   It uses stock hanging locations.  You do need to trim and weld the bracket to the tailpipe behind the muffler.   Over all, extremely nice quality.
