While I was at it I'd get the tappet blocks re ground to 2 inch radius, but really 30bhp isn't about what you do to the engine, it's about getting the inlet and exhaust manifolds working properly. All the bits you need are available probably off the shelf, but you need a good strong basic engine and that costs roughly the same whether it's tuned or not. Of course, 40hp and the whole game changes.
And I agree with Both Charles and Alan (again, not unusual either). We're all competitors and have been there and done that when it comes to learning that whatever you do, the basic engine should be as strong as you can make it/afford. Then get it running reliably and go on from there. You say you have the Companion. That includes Holly Birkett's Paper 'From The Special Builders Angle'. Whilst he didn't have access to the range of improved parts available to us today, so much of what he wrote is still very relevant all these years later.
