thick Exhaust gasket ?
Does anyone know of any manufacture that makes a exhaust gasket that is at least 1/8 (.125) thick. The gasket is round 2.15 inch big block chevy . I spoke to Mr. gasket and they dont have it. I have also checked my felpro books and they don't offer it.
The problem I'm having is the headers are hitting the valve covers .The headers are CMI split tubes . The valve covers are tall cast aluminum KE's. Replacing the valve covers is not an option, due to they are newly painted , and they are needed for the clearance for the stud girdles . I know I can grind the corner of the valve cover a little ,but I dont want to have to grind to much material . This is for a twin engine side by side tall deck blocks so exhaust spacers will cause the headers to hit.thanks for your help.

Use the Mr Gasket grafite gaskets and double them up
They have wire mesh built in.
I have used them for years and have never blown them out.
Make sure you keep the header bolts tight and it shouldnt be a problem.

Tom, Try CV parts, most of the high performance machine shops use their parts. I use the thick on my drag boat and have had no problems, Beware, you may have to retorque from time to time the header bolts. Is there a way you could heat up the exhaust and bend slightly away from your valve cover?
