Almost looks like a SBF head at a quick glance, wonder if there was any design/engineering overlap on the two engine types.
The Ford "Kent" engine went into production 2 years ahead of the Smallblock 221 V8 All V8 heads were crossflow but the Kent had intake / exhaust ports on the same side. The Kent had shaft rockers, and solid "mushroom" lifters [which made cam swaps a P.I.T.A] It is only the rocker covers that looked similar shape. The Kent engine was recognized early as an engine that flowed a lot of air and became a favorite for tuners. The 1000cc 3 main bearing engines would turn to 11000rpm in the F3 "screamer" era [they were limited to a 1 barrel carb] Here's a bit of music for you
You need to understand .... The Holy Grail of N/A race engines is 100 Ft/lbs per liter [this is a 4v F1 engine that has pneumatic valves, air boxes, tuned intakes, exotic lightweight parts etc etc etc. Back in 1964 these guys were getting 62-63 ft/lbs from a 997cc engine with 2 valves and a single throat carburettor And 11000 rpm from a 3 main bearing block and crankshaft. They only matched that torque/liter in the 70's with F5000 [formula A] engines with Lucas timed injection 510hp at 8500 rpm from Swiss built Morand engines Here's some more music
Boxing day was spent tearing the 1500-engine apart. Ready for cleaning, inspection and then off to the machine shop. I also got the inner intake ports cleaned up a bit so now the head is ready to be converted to unleaded fuel and some milling to raise the compression just a little bit.
I love the sound of those little engines and he did it proud on the dyno, inched it right on up until the red light came on for the RPM limit. Then let it wind itself back down. To hear a whole track full of those at full song would be something to record with modern equipment to do it justice.
