I am looking for a definitive description of where to paint the gold color (colour) on my cylinder head. Mostly where to stop painting relative to the inside (spark plug area) of the head.
Any ideas? I have various pictures but hard to piece together the whole story.

 

The entire valley and down the back and around the sides (intake and exhaust) but stop at the polished front and do not paint the small rough portion on the front! Not sure why some folks do!
