I just put on an ATR DS header with a thin coat of copper RTV. The thing leaks and the bolt are very tight. I am going to try a gasket. Do the chain auto part stores(Murray's, Auto Zone) carry these? Or where should I get them.
Did you clean around the ports? When I removed my stocker, there was a ring of carbon built up around the ports! I scraped the carbon off with a gasket scraper and finished up with some scotch brite.
I just installed the ATR DS header with a thin coat of ultra copper. I tightened it up and let sit overnight, then retightened again. It's been 2 days and no leaks!Just a suggestion if you can't find the gaskets.
Getting the dipstick back in was a huge PITA I should have clearanced the flange for the dip stick like the stock manifold
