Interesting. I have an APD 2 seater tourer 1933 , LC head and standard carb 4 speed crash box. It pulls like a train from my cul de sac up the bank in Severn Stoke (A38 a bit south from WorcesterJ mainly in top gear. Takes a while on the level once hot to go much faster than 40 mpg.
The other car is a RN with a 3 bearing engine with a LC head, Su carb and 4 speed box. It will when hot travel happily at 50 mph. But ascending the same bank needs 3rd gear. It was a far more sprightly performance with a HC head but despite skimming regularly blows head gaskets. So I reverted back to the LC head that was fitted when I bought the car.
They both have exactly the same feel of kickback when hand starting.
As they both feel happy trundling along I leave well alone.
