Hi all Happy New Year. I recently visited a gent that has this flathead engine. His brothers project and he p***ed away. It has a 671 blower on it and all internal parts are new in box. The heads are aluminum, but they are a 2 piece head. Another friend told me they were made out west and the idea was for better cooling. Anyone know much about these? Value? Nothing for sale, he has an emotional attachment to this. I was trying to help him out with any info. Thanks, Rick
Those are thick heads, not to be confused with Thickston heads. Cool parts find. That will make a nice little flatty. Not much room between that un-pruned blower and those heads. Usually you hear 2 piece heads and they are referring to those copper topped Champion heads. I cant see enough form your pictures, what brand are those?
Would be better with a “straight on shot of the heads”maybe showing a name or a little more detail. I realize your pics show the thickness of the 2 piece heads;I could be wrong but I would venture to guess they are owner bilt or homemade heads. Flatheads Forever!!
Some serious money sitting there and attention to detail. Those heads look a bit different from those posted by the OP. The heads posted by the OP have bolted on water outlet necks at the front. I’m guessing those heads are a one-off hand made affair.
Knew Norm Frick from the old Pate swap meet held west of Ft. Worth——hell of a machinist—-bought one of his homebuilt rt angle drive distributo units. Had a sbc dizzy turned down to fit the rt angle diameter and an all in advance curve suited for the flathead. 24degrees all in by 1750 rpm.
They look like CNC machined heads, and not cast. It is "common" to machine the heads out of 2 pieces of billet if one wants to retain the water galleys.
Would there be any water connection between the two chunks? And I wonder how the sparkplugs are placed.
Yes. The top of the bottom piece (opposite fire deck) would form the bottom half of the water galley, and the bottom of the top piece (opposite the outside) would form the top half of the water galley. See image below from an old HAMB thread of a set of Norm Frick two piece billet heads.
I don’t know about the Norm Frick heads but doing a visual comparison between OP’s heads and the NF examples I can see the notches machined into the fins for the two Allen screws that are at each spark plug location. The only major variation is that OP has standard V8 water outlets while the NF heads have the V8-60 style 3 port water outlets that attach to to the very top of the water jacket wall of the head. They are probably both made by the same guy.
