Richard,
You are right - I would be mad to want to lower the compression - unless
I was turbo charging it...
But no - it's nothing that exciting...
Last easter I bought a bargain 1300 cylinder head - ported, big valves,
~9.75 CR etc etc etc...
However, I've now got a bargain 1500 bottom end - lightened, balanced,
racey cam etc...
So, how to get the 1300 head to fit the 1500 head without having to buy
a ### head gasket...
