Brass flatheads ?

I have a pair of brass (?) 21 stud flatheads. Made by Federal Mogul. Are the from a boat? Anyone make water manifolds?

 

Yeah, they're marine all right. The water manfolds came with the heads; I don't know of anyone that makes them currently.

 

Those old things?? Aaah, just Holy Grails of flatheaddom. I'll give you MORE than current scrap prices, though...Federal Mogul.

 

I can't figure out what to do with them...no good way for me to put water through them. They LOOK to be perfect shape, I cant tell that they were ever installed on an engine.

 

no good way?? why can't you make up your own manifold out of pipe plumbing??

now that I take a better look at em. there's no water running through the head! definately not something you could run on the street

 

Don't feel bad, no one would be able to come with anything to get water in those old things. I'll hook you up, send them out to me. I'll send you back a set of the stronger cast iron ones with the hoses and everything already on them. I have plenty of these and wouldn't mind parting with a set to help you out.....Mike.

 

So...I suspect you are jacking with me, but in case you are not, I appreciate the offer, but I have a pair of aluminum ones I can use...they are kind of odd too. They are cast and smooth, with no ribbing, shaped just like an iron head, but not made by Ford.

 

They are indeed valuable items.

 

Yes rare. Too cool for anything I own anyway. But if you still want to trade I can start at the heads and build a car from there that would be worthy.

 

What's really interesting is the spark plug location. Way away from the top of the piston.

There's a set on the very famous McGee roadster! Very rear and sought affter!!! The guy who made replacments for the McGee roadster allso made replacement water logs...Roach.

 

I see another member was as ignorant as myself...he was thinking they were copper. And $5000 on ePay...WTF!!!!!

 

...and over the exhaust valve. There's a lot of theory involved here & some subscribe to plug-over-exhaust-valve positioning...looks like Federal-Mogul was one of them...

 

They were also marketed to truckers to help take care of overheating problems.

 

I suspect they're bronze (copper + tin), rather than brass (copper + zinc):
1. much, much stronger (bronze was the sword material of choice for thousands of years until steel was invented)
2. excellent cooling (replaced by aluminum for weight)
3. much more corrosion resistant - the 48" NYC water gate valves put in after the Civil War still work
