Chris,
Well, I should have read your original post before replying. Seems
you already knew about the differences in combustion chamber volume.
I would think that if you use stock flat-top pistons from a pre-68
engine, you should be able to get 9.0:1 without shaving the head. I
think 9.0:1 was a stock ratio in the pre-68 engines.
Are you planning to replace the rods? I understand that you can use
any pistons in any year engine, as long as you use the appropriate
rods, since bore/stroke was always the same for the 1800 engine. I
would order rods and flat-top pistons appropriate to whatever year
your head was made, and you should be all matched up.
