I ran a Riley 9 a few years ago and Riley people are finding that modern gaskets do not last anywhere near as long as proper CA types. My 9hp blew a gasket between 1 and 2 cylinders when I was taking a prospective purchaser out for a test run! Fortunately, we were only 1/2 mile from home. Needless to say, he didn't buy the car but he did purchase it 6 months later when I had changed the gasket and bedded it down again.
The Riley gasket came with detailed instructions about tightening the head down in stages and checking torques frequently in the first few hundred miles.
I regret selling that car, it was a very nice example, '34 Kestrel with a manual 4 speed gearbox.....
I haven't, personally had any problems with Seven head gaskets; the only one I've blown recently was on a '34 AH tourer and that turned out to be due to faulty head studs.
