Yes that is what caught my eye. A picture is worth a thousand words.
Then when you think of all the head and piston manufactures (especially twisted wedge and Cleveland types SB), the valve reliefs and heads are not always going to match.
Just one of those light bulb moments for me. I'm not afraid to admit I learned something or didn't truly understand it in the first place.
Even though I was aware the other dimension (radial) existed, I always thought one dimensional in valve clearance. I was fully aware of valve shrouding by the cylinder wall, and that some applications people notched the top of the cylinder wall. It just never clicked that the radial clearance needs to be checked until I saw that picture.
