Highly regarded as the ‘go to’ shop for Ford and Lincoln flatheads, H&H Flatheads has re-introduced the rare DIXON sohv heads for the flathead Ford V8.
“Hot rodders are always looking for something different and the single overhead exhaust valve DIXON heads are definitely different.” Said Mike Herman, owner of H&H Flatheads. “They have an amazing pedigree having been first successfully run at Muroc Dry Lake in 1938 when on July 3 the Dixon-Richards entry set the top speed of the meet at 120 mph. Fast for its day.
“Basically, the DIXON heads relocate the exhaust valve out of the block and into the head reducing overheating and allowing for vastly improved exhaust gas flow. And, of course, they also give you four rather than three exhaust ports for a more contemporary, balanced look.”
Cast in Los Angeles from the highest quality tempered A356 aluminum and CNC machined, the DIXON heads are designed to fit the desirable 1938-1953 59A and 8BA 24-stud flatheads. The heads come complete with Isky valve springs, 1.5-inch diameter stainless steel valves, adjustable push rods, lifters, custom head gaskets and a pair of exhaust flanges. It’s everything you need to make the conversion.
Besides an ever-widening range of speed equipment, H&H Flatheads also offers full machine shop services for classic engines; everything from hot tanking, acid dipping and pressure sealing through all stages of machining to short or full-block assembly.
