Have you guys ever come across a set of heads with this casting.
After-market. Carried by the parts houses back in the day.
Does the FOR and FOS stand for anything and do you know what years they did these? Thanks
The letters were probably the manufacturers ID#.
I remember as a youngster there were stacks of these heads next to the back doors of a couple of parts houses I frequented. This was in the mid 50's, heads likely had been there for many years.
Yours are likely a "fit all" head for '38 to '48. Looks like a casting date on your heads, but I can't make it out.
I recall Santa Clara auto wreckers had some of these...they said they were 'Super heads', I was 12. Looking at the combustion chambers, I nearly compromised my future welcomes there, 'enlightening' them as to what they 'didn't have'. (I was a avid reader of HRM, recalled the great Don Francisco articles, "Building a flathead the RIGHT WAY". Don and Roger Huntington covered these areas (cyl heads, combustion chambers) in detail...)
I did see some out at the old San Jose Speedway in '55-'56, on some 'also-rans', but the big guys had Canadian aluminum heads, Merv Furtado or Chris Seevers milled, filled, flycut...
Are they worth running if they are cheap? I just don't want some badly cast head on my engine.
They are/were just a replacement head. No advantage over a stock Ford head.
