captden29 Posted April 24, 2019 Report Share Posted April 24, 2019 I am getting ready to put them back on. do I need any gasket cement? I think not, but I am unsure. I separated them, so they need to go together again. was able to leave the heat riser in free flow position. no amount of heat and penetrating oil will get it to turn freely.anyway, the spring broke and the flap is welded to the rod. this was a big job because of all the cleaning and scraping 65 years worth of crud. thanks, capt den Quote Link to comment Share on other sites More sharing options...
Doug&Deb Posted April 24, 2019 Report Share Posted April 24, 2019 You don’t need gasket cement. New gaskets will suffice. Hand tighten the manifolds together until you have them bolted to the block. Otherwise you’ll crack something. Quote Link to comment Share on other sites More sharing options...
captden29 Posted April 25, 2019 Author Report Share Posted April 25, 2019 thanks doug/deb. after I hand tighten them together and bolt them to the block, is that when I torque it all up? the last time I did this on a different flathead I did not separate them. easy back on that way. capt den Quote Link to comment Share on other sites More sharing options...
Doug&Deb Posted April 25, 2019 Report Share Posted April 25, 2019 Yeah, tighten them after you’ve tightened them to the block. You don’t have to over torque them. Don’t ask how I know how easy it is to crack a manifold. Quote Link to comment Share on other sites More sharing options...
