Thanks for everyone's input. I'll check both heads and pistons and work out the comp ratio. Boucher.

And this is where a good book about mechanical mathematics, or even simple hot-rodding, really helps. MikeV

Thanks Mike , Palmer. I cc'd combustion chamber with engine assembled. I measured 29ml which is about 13.9:1 comp ratio. (With 1.00mm squish) A bit too high. Will check it again once the larger valves are installed. Boucher.
