Yes Ron what J and Red have stated, I bought my T knowing zero @ #1 and 48-50 for the other three.
I pulled the head and did get the exhaust valve to move again but after cleaning the carbon and looking @ the valve seats I had some work to do.
New cam, valves, adjustable lifters, timer, wiring ect but... it's running and driving again after a long siesta in a local shed.
Just an FYI, the good copper head gaskets are/have been on back order for some time. There now being promised hopefully B4 turkey day
Good luck and let us know how you make out.
