Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Leading evidence: 'latter' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'latter' (1 discussions; 0 report identifying it and 1 suggest it). No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Leak has been fixed, my concern is what's going one with that one exhaust port? Could I be running hot on one bank causing the header flange to warp or could the cheap header flange not have been flat and it just manifested itself over the 800 miles I've driven it (not sure when the PO installed the headers)
I got a set of Agency headers from another member here. When I got them and installed them on my car, the drivers side had a nasty leak. I took them back off and brought them to a guy I know at a local machine shop (I figured it needed to be milled flat). It turned out it was just slightly twisted. He put it in a vice and twisted it straight, then put it on a large belt sander to finish it off. Perfect! and he didn't even charge me
It looks like yours needs the same treatment (without the twist). Make sure the gasket is good as well...
A machinist "straight edge" is invaluable in instances like this. A good flat file and a window pane with some valve grinding compound along with a little time will make perfectly flat surfaces the "old school" way.Oh yea, and you will need some feeler gauges.
