heads are alum. w/ 48-6049 + 50 ford script and an HT to the right of the script. What does the HT stand for.???? ken ct.:)
 
It's just a guess but I'd say heat treated. A lot of aluminum castings and forgings go through some hardening processes.

Ken, another guess is "high temperature", maybe an attempt by Ford to make the flathead run cooler. Scott
 
Thanks guys but already thought of those ,would like a definite answer from somebody not a guess. ?? LOL ken ct. Why is it so marked and others ive seen dont have this marking.Its definately factory. There raised letters [not stamped in].
 
Ken, I am far from an expert but those seem tohave a smaller combustion chamber and wonder if they were for higher altitude areas.
 
Dont know if the CC is smaller or not,and not intending to remove them if at all possible.thanks ken ct.

Ken, Did you look in the 1935-36 Ford Book by EFV8C/A? I'm thinking I read something in there on this or maybe I'm thinking of a past Fordbarn post that explained this HT marking as well as other markings found on the original aluminum heads. If the info is not in there, I bet Don Rogers would know exactly what the HT means with no guess work. Send him a personal message with your questions and then let us know what you find out.

In the 33-34 version of this book on page 3-9 it say this means" High Temp " . Not my info just an observation .
 
HT does mean Heat Treated. Some archive drawings have this notation and some don't. There were 3 companies supplying heads and intakes to Ford (Alcoa, Bohn, & National Bronze), so the markings might be a manufacturers preference.

Thanks Don you beat me to the PM i just sent you. Just disreguard it. I still am confused why were some HT and some were not. ken ct.:)
 
I know..Its gets frustrating trying to figure why Henry did some things onetime, and then not! I wasn't looking for this type of inconsistency when I was looking at the heads at The Archives. Oh well...Someting for another visit!!
