Jim, Remflex gaskets, _http://www.remflex.com/_ (http://www.remflex.com/) Got them on an old set of Hookers on the Hemi, everything else leaked (flanges not so great) problem solved. I know its probably too late, but if you have to do it again try these, a little pricey, but worth it! John Althaus 64 Savoy Hemi 4spd 214-673-7540 cell In a message dated 6/27/2008 7:16:16 P.M.

This has served me well in the past, but just checking ... has some other product come out in the last few years that is thought to be an improvement?
