Shimming the tappets

Setting the valve clearances on the XK head is a time consuming process that requires patience. I have finished mine. It took me about 4 hours, never having done this before. Each side had to be pulled down about 4 times. I'm pretty satisfied though and the inlets are all 4 or 5 thou, and the exhausts 6 or 7. Once the Cometic head gasket arrives the head can go on, and it's done!

Rather than taking photographs of this process, instead have a look at what you get for $50 for an XK head. This is off a 420, and seems to have been stored in a dam.
