You will need metal to metal contact when it comes to the long nuts for those manifolds. Have a machine shop take a lite swip across the mounting surfaces and make sure your head mounting surface is clean. Then bolt them up. I cannot express this enough though...NO GASKET BETWEEN THE MANIFOLD AND HEAD MOUNTING SURFACES. Not even any copper sealant..period. You will be asking for problems down the road. Just ask me how I know...besides...Ma Mopar never used gaskets when the cars were new. Must be something there....Good luck/cr8crshr
Yeah i decided not to use gaskets, as the stock setup didnt require it. WIll check the surfaces for trueness before i bolt these up... TY
