ummm 66 bonneville head....... that is not the right answer as to what has been done to them or why. the lead in chamfer was done by the
factory
but yes on the spigot thingies
hated the idea of throwing that head away and it did take a bit of carving to unshroud the valve without giving up too much compression
I've also never been too thrilled about how sloppily and off center the british cast in the valve seats
those of you that have had Japanese and other better Euro Iron apart will recognize how miserable these castings are in this area alone
really takes a lot of work to make them useful
lap and full polish next
shiny may actually be my favorite color
