gundogC3 Posted January 26, 2005 Report Share Posted January 26, 2005 If you are running a CHEVY-go buy two sets of stock manifold gaskets, glue the paper side together, install em metal side out on both side's-won't leak and can use em over and over and over- cheap too! Also get a straight edge-check your flange to make sure it's true first, or no gasket will survive. Link to comment Share on other sites More sharing options...
flying 33 Posted January 26, 2005 Report Share Posted January 26, 2005 I second that on the stock gaskets, also you mat want to check to see if the headers are warped. if they are a older set of headers it could be possible. as long as i don't have to pull the header off during the season i have gone all year on a set of gaskets, do a bolt check often and when you tighten them start in the center and work your way out. good luck!!

Lane77 Posted January 26, 2005 Report Share Posted January 26, 2005 You may want to put a small beed of Copper silicone on both sides of your header gasket. it is a little messy at first , but it works like a charm everytime. The copper melts and conforms to the surface even if the headers are abit warped. Jusst an idea. It works for me. Bryan Lane Link to comment Share on other sites More sharing options...
Truck99 Posted January 27, 2005 Report Share Posted January 27, 2005 The best thing we did to stop header gasket blowout was buy a better set of headers with a thicker flange. Straight flange= no leak. Before that, we used the copper silicone like Lane77 suggested, and that worked well. Link to comment Share on other sites More sharing options...
dancer52 Posted January 27, 2005 Report Share Posted January 27, 2005 No one uses the copper gaskets or alum.... I have for a few years without any problems. Link to comment Share on other sites More sharing options...
1-Crew Posted January 27, 2005 Report Share Posted January 27, 2005 1. After you torque the bolts the first time, heat cycle the engine and torque them again. You may need to tighten them a couple of times over the first week but eventually you will get the gasket compressed fully and they will quit moving. 2. Make sure the rest of the exhaust system is supported well under the car. The headers should only have to suport themselves, not the rest of the pipe and muffler. Stock gaskets (metal/paper) work as well or better than the all paper ones that usually come with the header - if the bolts don't loosen up. If the bolts loosen up, no gasket will survive long..

MIKE65 Posted February 16, 2005 Report Share Posted February 16, 2005 If you take a new set of header gaskets, get some aluminum or dull aluminum spray paint hold the gasket up by one corner spray both sides until its dripping off then install as quickly as posible, tighten bolts from middle out and forget about it.

supertx Posted February 25, 2005 Report Share Posted February 25, 2005 We have not ran header gaskets for years.We do have good headers and the header plate is flat. What we do is just put a bead of red silcone around each cylinder and the a little on the threads of each header bolt works great never had a problem in 20 years doing this Link to comment Share on other sites More sharing options...
