Alright, so I am finally ready to sit back and ask the experts for help.
I put some summit headers (g09040) on my '67 satellite with a smog 360, and couldn't get them to seal. Took back off 4+ times, tried percy's gaskets, fel-pro, red/black/copper rtv's, the works. Loud ***, leak, sounded like it was coming from everywhere. Every. F'ing. Time.
I worried that perhaps my smog hole plug job (had a couple tap breaks, plugged w/j-b weld) wasn't complete, and that was the leak i was hearing. No indication on the gaskets of any smoke/impression by the smog ports, they still looked plugged, nothing appearing to come out under the header flange. I can't be 100% sure because the flange covers them, but i don't think they are the culprit.
SOOO. I finally gave up and dropped $$$$ on TTI headers and full system. I wasn't crazy about the ground clearance on the summit headers anyway. Great product, easy install but i still have the same loud *** leak sound, seems to be coming from everywhere. Can't isolate to one side or the other. Currently have Remflex gaskets, w/no sealant. 20 ft/lbs as recommended.
They LOOK sealed. The gasket is crushed. Spraying soapy water around while running, i see no bubbles. Where the hell is the sound coming from? It is such a loud racket I can barely hear the exhaust note coming out 2.5" H-pipe duals w/dynomax. It sounds as if somehow one or two cylinders is way louder than the others and the sound is just echoing in the headers.
Questions? Recommendations for next steps?
