while reading the replies, I had that same thought.
BUT, that would be an inconvience so, I will ASSUME the motor will be installed level and thus parallel with the top screen.
while I didn't ask more details, when I spoke to the guy building my engine, I think he just sets the intake runner flange faces level and cuts what ever angle was on the carb base off.
If it was the opposite, (putting a flat based intake in a Mustang), then measuring the motor installed angle might be a good ideal
