I can't seem to keep exhaust leaks from springing up on our '62 300 413 block. The heads and manifolds were surfaced at the rebuild, 25,000 miles ago. I put in all new studs and use flat steel washers with brass nuts. I torque to the manual specs and re-torque once heated up, then cooled down. I think I use FelPro manifold gaskets. Any secrets I should try? Matt Allyn Exec. in Charge of Prod. Granada America 323-785-2129 office 323-785-2151 fax 562-533-2551 cell ------------------------ Yahoo!
