Replacement spark plugs for my flathead V8.

I used the plugs in my Offenhauser heads, they were recommended over the champions as the threads were correct for the application. The DUI distributor I am using required 50 to 55 Degree plug gap and I wanted a plug that could handle the increase in gap and threads that I felt better about using. Just personal prefferance.
