I am running both the 1931 saloon and the Ulster on Dave Dyes Ricardo head. The saloon was previously on a bronze Nippy type head and the improvement upon fitting the Ricardo head is very noticeable. The weight saving might also be improving the power to weight ratio!
Go for the Ricardo head, it will pay dividends on any engine. Dave will machine it to suit your engine re compression ratio etc.
I have the larger 18mm plugs in mine, partly as they are more period looking. If your engine is a bit worn and prone to oiling, go for the 18mm plugs, they are much more tolerant.
