You beat me Tony, 6500 miles a year equates to 180 mile every day which leaves little time for other activities. Whilst I've achieved 50 MPG in an RN saloon but not on Malcolm Parker's runs.
I have one car which has had various heads fitted all using the old joint (a modern non asbestos one) it just requires both faces to be flat.
