I would first like to thank all that contribute to this site. It is invaluable to the new Cruiser owner.
My question is regarding the exhaust manifold on the 3FE and its associated gaskets. I have taken the manifold off of my parts truck, cleaned it up, purchased the Felpro gasket set (exhaust and intake), and the donut gaskets to the down pipes. When dry fitting everything together the donut gaskets seem a bit sloppy, and there isn’t much of a gap between the flanges to close when tightening. I know this is a notorious problem spot with blown gaskets and I am wondering if anyone has a solution. Is doubling up an option, or is there some sort of heat treated gasket gunk to add? Regarding the manifold, when laying a carpenters framing square across the face there seems to be a slight gap in areas. Does the thickness of the gasket and the torque down process take care of this on install, or is it worth machining?
Thanks again.
