Default Re: AutoLite 216's in Offy heads

I have offenhauser heads on the French motor in my roadster. I run 216s. A few years ago I did what I thought at the time was the clever thing to do and chamfered the holes from the underside. It runs great and never caused me concern. If I were doing it today I might reconsider and try and use a longer plug.
Fingers crossed I'll get away with it.
Mart.
