Just got a recent rebuild running. 59 AB block 3 5/16 by 4" stroke. Offy 375 heads, mild cam of unknown origin. Using AutoLite 216's cus I had them. It misses now and then, pulled plugs to find a bit of carbon. Also I am thinking that a longer reach plug would be better. Not sure how smart it is to have spark plug hole threads exposed in the combustion chamber.
