Is there a way to check the cylinder head thickness, to see if it has been milled. This is a 21 T

If the head has been decked a few times in it's live, you will never be able to work out how much but if milled to try for more compression is another story, check the encyclopedia for head changes.

Should read life, not live. Sorry.

Chuck,

In a private email to me, according to Steven Lang, the stock high head is 2 11/16 high which is the distance from the surface of the head to the face that the head bolt sits on. Measure this distance using a set of calipers to see how much has been removed. The head can be faced several times and if the surface needs it just take off as little as possible. Mount the head on the mill using head bolt faces as the mounting plane. My low head has had quite a lot shaved off and is into the water jacket in two places. These holes get closed off by the head gasket so I don't have any leakage.
