Kurt, I am 99% certain, there were no Mercury (only) cylinder heads installed upon the 59 series blocks.

Re: 46- 48 merc heads
There are no known distinctions (or differences that I know of) between 1946 - 1948 Ford versus Merc engines. As such, you can't tell one from the other (they're the same).
Now, when I say that . . . somebody will tell me they have an original 46 Merc where the engine was painted purple . . . (There are always outliers it seems!) LOL |

I seem to recall they were all painted blue regardless of whether they were to be installed in a Merc. or a Ford.

Re: 46- 48 merc heads
There are quite a few nuances that are used to tell a 39 - 42 Mercury engine from a Ford. Also, there are WWII engines that are 239 cubic inches and closely match the 41-42 Mercury engines.
I won't try to get into all the differences - plenty of sites have shown the blocks, the raised intakes, the coolant holes, the 'pencil test', etc.. For many flathead performance nuts, the 99A Mercury block is special . . . even though it really makes little sense to believe it is any better than a good 59AB 239 block. I have a 41-42 style Merc style engine in my 32 Cabriolet - it was an engine built for WWII military applications (dual-sheeve pullies, special oiling system mods, etc). |
