Over the weekend I had the opportunity to get two spare heads that a friend of mine wanted to get rid of.
Head #1 is the Original head that came with the car
Head #2 is a head he had on the car with hardened exhaust valves
When I got home I noticed that head #2 had a screw plug that head #1 did not.
I checked my TR6 and noticed that mine did not have this plug either.
Why is the plug there? Is it a later model? Can I use it on my '73 TR6?
Everything about the two heads looks identical except for the plug.
I did check my Bently manual and did not find anything... thanks for any help!
