Missed on this combo?
Epoxy is called Goodson 2 part cylinder head epoxy. Mixes to consistency of soft clay. He told me a wet finger will do perfect. Might not even need sandpaper (I will). You have 15 minutes to work the stuff. Ordered it today.
You can't tell, but that unmachined black area is a good .175 taller than the surrounding port. In his words, just a mess....
Geez, if only I knew.
