I am trying to set up my 4 valve Rajo, I need 4 unserviceable 2 piece valves. They will be cut off and drilled out to fill void where original valves were under the head gasket. PM me for price and shipping. Thanks Sam
Sorry Sam, for me, all of my two piece valves are in service making me happy. Waiting to come apart. ;-)
He is using the valve head as support for the gasket between the head and block. My OP, this is not needed anyway. Plenty of overhead T's running without support there. Once the modified valve is there it would need to be locked in place to keep from shifting around when the head and gasket were installed. Besides, by time it was worked down to be level with the deck and a hole drilled for the push rod there would not be much left of the valve for support. Somewhere in the back of my gray cells I seem to recall seeing something about filling in the port and drilling a hole for the push rods, lead maybe.
I have supplied about 30 new copper shim head gaskets for the Rajo 4 valve cylinder head. Everybody seems to be happy with them so far
The 4 valve is a different animal than the other overheads. Blown head gaskets has been a problem with the 4 valve heads. There are several ways to support the gaskets. Using valve heads drilled for the push rods for gasket support, and pouring the ports full of lead and machining them flat as well as making a hole for the push rod to go thru are a couple of the fixes. I have a couple of Les Schubert's solid copper gaskets that I hope to use this fall with my four valve. The solid gaskets may not need the extra support. I know that Seth blew his head gaskets at least 2 times (maybe three) before he finally used the valve heads for support. I have not heard of any failures since then on his engine. Sam, send me an e-mail to dobro(at)artelco.com. I will look and see if I have anymore two piece valves. They are free, you pay shipping. Should fit in a small flat rate box.
Donnie; Thank you for the information.
I wrote a brief description of a solution that I have used and had seen on several overhead T's in the past ( see your classified ad for 2 pc. valves) ...I think that pouring the valve ports solid and machining the material flush creates a simple durable gasket surface with very little effort ...also blocks off the port on the outside for appearance ...always an optimist...gene french
Thanks to all of you, and MTFCA forum, Les could you send me your contact information to get one of your
gaskets. Thanks Sam
I sent you a PM
