Seem pretty good. Had to bump them to clear the clutch z bar. I'm hoping they'll hold up ok, I bought them for shape rather than cost, I've had mine ceramic coated, and I put bungs in mine for o2 sensors too. Will find out soon I suppose, haven't fired the engine yet. They have lots of good reviews though. I did notice last night that the air con compressor bracket won't fit with a spacer on the bolt like it did with my previous (Hedman) headers, would need to give it a small bump there too, but I want a different compressor bracket anyway given I can't use the brace back to the intake manifold with my intake either.

Wow, I had no idea there was a header option for our cars that was that reasonably priced...
I'm shocked that they fit with a rack and pinion set, too. A pretty ridiculously good deal. @ $122.
I wanted coated headers because of looks, longevity, and because I really need to keep the heat down as my engine build is going to be pushing 10.2:1 static CR and 8.1-8.5 dynamic CR depending upon what CAM I ultimately select. I got the flowtech ceramic 31106FLT for $274.66 with free shipping after using a coupon code @ Advance Auto that knocked off $50. -They fit with basically anything you can throw at them, but they're still $150 more expensive than the summit brand.
MetalHead what did it cost to get them coated? -This really might be the cheapest way to get a good fitting set of headers for these C3's PERIOD.
If you do decide to get them coated then add your O2 bung just AFTER the header so that you don't damage the rust-resistant coating.

I put the bungs in my headers before I got them coated. Coating in Australia is expensive, it cost me a bit under $200US for the coating - but that's inside and out and a much higher quality coating than comes on most factory ceramic coated headers (the flowtechs for example I have seen pics with rust spotting through the ceramic after a couple of years). And I wanted black. Normally it's recommended to put o2 bungs in before the flange at the end of the header, to avoid any leaking at the joints affecting the readings. I think from pictures that these are the same as one of the flowtech models but without the ceramic coating.
P.s. That engine is 10.9:1, with a 242@.050 .558" lift cam, ported Edelbrock Performer RPM heads. Hopefully it will work pretty well and the headers will hold up.

Great fit. No issues there at all. Had a few leaks in mine, but nothing better gaskets didn't fix. Decided I wanted a different look though and bought a set of SS headers to replace them with. I had stripped and then coating my Summit headers with VHT primer, color and clear coat. Stands up good as long as you do not scratch it during installation. Good budget-minded headers.
