i followed the instructions posted by dvw in the thread
my combo engine is a 440 with iron heads and had the stamped-steel valve covers which i ended up getting rid of
i tried different combos but ended up using some mancini racing aluminum valve covers and thick blue moroso valve cover gaskets (also purchased from mancini)
dvw posted to use 3m weatherstrip adhesive to glue the gasket to the cover. i thoroughly cleaned the covers with rubbing alcohol and let them dry before applying weatherstrip. i ithen layed a bead on the cover and then a bead on the gasket, let them setup for a few minutes, then mated the two together. i put some electronics engineering books and some managerial statistics books on top of the valvecover/gasket combo for a few days
in regards to the tops of my heads, i removed the old stamped steel covers and soaked up the oil with some paper towels over night. i then made a cup of engine degreaser and scrubbed the tops of the heads and soaked up excess degreaser. i did a few iterations of this process. i then moved onto cleaning the tops of the heads with rubbing alcohol using qtips to help get hard to reach areas. this process took a few days before i was satisfied that all was clean and dry.
i then moved onto applying a thin coat of black rtv to the top surface of the head and let it dry. i came back the next day and applied another one. i inspected the bead and ensured it did not peel off.
now came time to install the covers. i applied a thin coat of black rtv to the surface of the gasket that will meet the head. then i installed each valve cover to thier respective heads with some arp fasteners and torqued finger tight and then some - very specific. i think 8-11 inch pounds
i let it all sit and fired up the 440 the next day. i inspected the engine with various mirrors and some flashlights.
it took a few days but no leaks.
thank you dvw
ooops. did you say exhaust?
