My 34 Eight came with a similar cylinder head on it when I bought it, and I replaced it with the correct one in part because it was incorrect, made an awkward fit for the upper radiator hose, but mostly to get away from those damn 10mm spark plugs! I doubt you'll ever notice the slight increase in power which might result from the higher compression, assuming it and a correct replacement head have both been milled the same amount, or not milled at all.

Packard covered the subject of shutter vs head thermostats in a paragraph in the 37/38 shop manual which perhaps you should read. In essence it says that to get the best hot water heater (remember, the hot air heaters were still offered thru 1939) results, use a 160 cylinder head thermostat along with a 150 shutter thermostat, but only with the 150 shutter stat. (The 37 Super Eights used a 160 shutter stat, the inference is that it is not recommended for use with a cylinder head stat).

As to the window channels, I'll take a look at those on my 34 (original car) and if I see anything worthy of comment, I'll pass it along.
