    Big Block Exhaust header gasket recommendations?

    I just use the regular old felpro exhaust gaskets from the parts store for my headers. Never blow out, only time I have to swap is if I have a header off the head. I have all studs and star washers under the fine thread nuts.

    Found the source of my bottom side noise.

    Well I ordered a pair of summits 2 chamber flow master knock offs. Had to add a set of brake shoes and a tee shirt to get to $ 100 and get that free shipping lol. The comments / reviews on the muffs were loud and drone, they should be perfect. :thumbsup:

    Will Paint Adhere to Aluminized Tubing?

    When you paint headers or exhaust manifolds & pipe your heat rated paint needs to be tempered / baked on. No paint will hold forever but doing a heat cycle with cool down a couple times before road use will help it last for awhile. Eastwood used to make a cast iron / grey colored exhaust...

    Exhaust Manifold dripping Anti Freeze

    all of your exhaust manifold bolts go into coolant on a big block. Sometimes permatex will not do the trick on a wet hole. You need to drain down your coolant below the heads , blow them out with some air and use a heat rated PTFE pipe sealer / pipe dope. If its steam rated its good. put it...

    USA quality control is not even close to what it once was in the auto parts industry.

Headlamps , tail lamps , fenders and hoods , doors...

    Flex Pipe Question

    Dont use it. Just have a exhaust shop bend a pipe that fits. If its to the 45 degree stage you may wish to move back down the pipe and start the transition sooner to get to the angle needed. Also headman has a ball / socket 3" set up to line up miss matched exhaust.

    Header Gaskets question(s)

    As far as header gaskets I have had the best luck with regular fel pro metalic exhaust manifold gaskets. Re tighten once after the 1st heat cycle, star washers used for lock washers. That and having rubber ended pipe hangers so things can flex a little.

    Asking for a friend....Headers?

    Schumacher Tri Ys , they are not a long tube so they do not make the same power increase, But they are better than cast iron manifolds and are no problem to install. easy plug changes, and you can use full size or mini starter. 67 coronet , ps, & auto column shift, the shifter bell crank...
