Thanks all for your thoughts. I think the consensus seems to be that I'm on the right lines. The Chromidium block has had liners fitted and these are bored +.060" if memory serves, so some work needed there.
My primary concern is to preserve the crankcase, which is at risk if the crank lets go and/or if the sports cam continues to try to separate it from the block - hence the replacement of these items. Interestingly, Paul Bonewell reckons his fast road cam will give similar performance but with a much less aggressive action.
Forgot to mention I shall be boring the oil pump +.020" and fitting new steel timing gears from David Dye.
