With a high-lift cam, wonder if the valves will hit the spark plug ground strap? Sure looks like it. I would test fit on an engine where you know the exhaust valve is at full lift. Make sure you do it on the side where the valve is higher from the deck.

FYI: Given the valve angles/heights are different side to side, there was a time when Edelbrock actually made a left and right head - the cast chambers were different side to side. I bet the new NC machined ones are non side-specific.
