So the head is back from it's compromised valve job.  Yep, and making it better wink

 

Photo below shows the head sporting its new valve job, and it's compromise.  The compromise is the top cut couldn't be any larger, or smoother do to the head gasket fire ring placement.   One area NOT to be compromised!

 

The results is a top cut that is only .050" wide, and is "sunken" into the chamber by .062"!

 

 

Using a 1/8" "tree" burr as a file, I slowly reshape the ledge

 

 

 

With the ledge now removed, flow should be undisturbed

 

more to come....
