[ERA Chas]

Me too Allen. I should have know this from H.S.
I think there's several basic areas like this I should (or would like to) know a lot more about.
Barry's book is a great reference for me and surpasses Christ's. But I often refer to Christ's because the dated nature of the info and techniques are very basic now. Closer to 'back in the day'.
They never had intake gaskets as good as these then...
