Which remflex header gasket - 1 3/4" headers
Fighting a header leak where the header bolts to the head. Going to try remflex gaskets and studs. There are two remflex part numbers, one for 1 3/4" and one for 1 7/8". A quick measurement of the exhaust port on the head shows 1 5/8", I would assume the 1 3/4" gasket would the correct one to use. Anyone use these gaskets and if so which one?

I haven't heard of these gaskets. I use the stock gm gaskets. No problems on 2 cars and 8years. I suspect one of you header flanges is warped. Have you put a straight edge on the header flange to check for warpage?

I don't doubt the flange is warped, just trying to fix it on the cheap BC my build is costing a lot. Some c6 guys have to use them on their kooks, I have xs power headers so you get what you pay for in my case.

Had them 4 or 5 years I can't recall. Bought new and I believe was one of the first sets shipped. They changed the design so I highly doubt I get anything from it. I will be changing to ARH soon enough. A welding shop will be removing the AIR tubes so I will have them check the flange and if its not too much work fix it. Paired with the remflex gaskets I should be OK for a season or two.
