My experience of the Dave Dye Ricardo head is the fitting of them to mildly tuned engines, not out and out racing engines. The SWB saloon has been fitted with a Ruby head, a wedge planed early head, a bronze Raeburn 9E1 head and latterly the Ricardo head over the 20 years it has been on the road. The Ricardo head is by far the best. The engine is quieter, smoother and much more responsive, especially at the lower end. The engine has larger (Mini) inlet valves which probably didn't suit some of the other heads used. Standard cam with flattened followers.
I opted for the 18mm plugs as they look more vintage and seem to be less prone to fouling. I generally use old spark plugs, some must be 50 years old, they seem to work better than new ones! Being from Yorkshire you will understand my philosophy.
