270 Initial Valve Adjustment

[mudflap]

Hi Sabre1,

Hi my exhaust valves have GMC heat 3835105 has anyone ever encountered these and where could I get more

Not sure I understand what you mean by "heat 3835105"...

If you are looking for CCKW exhaust valves, the GM PN is: 2137374. These show up quite frequently on auction sites such as e-pay. A search based on this PN should allow you to locate some.

Note, that I have seen other PNs for the later civilian 270 GMC engines. Not exactly sure what the difference is.

Best Regards....

I take the valve cover gasket and 'glue' it to just the head with Permitex Form A Gasket and let it dry with the valve cover bolted down in place overnight. The top of the head is flat and the engine is tipped back slightly. The oil likes to just run off the head and make a mess. Gluing down the gasket makes a little dam to keep the oil from just running off.
