Petronix dist clearance prob

I have raised port victor knock offs and a fast 2.0 dist. to control the timing . The only problem is/was , fast used a short chevy dist. w/ a mopar flat end on it , doesn`t even come up past the valve cover , it was grind city , but all worked out well.
Moral of the story, if u do the same set up , use an MSD locked out 'MOPAR' dist .

is the head “ thick” in that area ? Can you grind some without getting into trouble
