Petronix dist clearance prob

So I am installing a Petronix dist in my 440 and it just hits the alum head on the pass side. Doesn’t seem to hit by much , but keeps it from sitting flat on the base. Can this be “ clearanced” or just no way to use this setup. I know a lot of people us MSD. But I have this new Petronix and would like to use it. Any ideas ? Thanks
