No just regular pressure. I have used Air to blow out the Drains at front and back but still not draining at rear which is where its dripping. The drain goes straight in but how far back into the Head is the "down" run?

  

Both heads have s drain hole at both ends.
The drivers side head would have the rocker drain tube at the rear and the passenger would have it at the front.

Are your rockers with higher flow or pressure oil than stock? Possibly overfilling the heads?

Update.   Still dripping Oil after blowing out drain Backs. Oil is not draining as fast as it should. How far back in the Head is the "down" for Oil. Not at the end so it must be around middle somewhere. Must be something stuck blocking the "down" opening. Going to try a piece of wire if I have an Idea where the opening is.

  

John Mummert lists the Neoprene Ones on his Website. As a matter of fact those are the only Ones He lists.

  

Thanks Ted. I didn't know the early Gaskets are thicker than the later Ones. I pulled the Covers and blew out the drain holes. See if that helps. Oil shouldn't get high enough on top of Heads to cause leakage. I did find some small Pieces of old Cover Grommet around the Drain back Holes so maybe some got down inside the Head. Take it for a long Drive and see if it still drips.

  

Anyone use Gasgacinch?  I wish this question was posed a week ago, because that's when I ordered Gasgacinch.  

The Best Gasket full set of gaskets includes two different pair of cork gaskets for the Y.  The thin set with the tabs is for the 1960 and newer tin covers while the thicker set without tabs are for the both 1954 thru 1959 steel covers and the aluminum Thunderbird finned covers.  I have no leakage issues when using the thick gaskets on the aluminum covers.  I will glue the gaskets to the covers using small dabs of ‘black’ 3M trim cement and then a thin film of white grease on the surface that contacts the head rail so the gaskets don’t stick to the head.

FWIW, this is the way I do my Thunderbird aluminum valve covers and over the past two years I have been very satisfied. I use pretty much the same method as Miker.

I glue the gaskets to all the cast aluminum covers I’ve used. Then use a little grease on the head side. Stops them from slipping, and seals but let’s them release to set the valve. I think Ted has something on that, hope he’ll chime in.
