Having established what the bore and stroke was the lads calculated the
size of the combustion chamber to give a modest 4-1 compression ratio.
Then we started on the cylinder head. the water jacket was milled in the top ,leaving support for the valve guides and enough area to allow the gasket to seal.
The combustion chamber was turned out and the ports cut on the mill.
Most of the lads preferred to use the larger machines in the shop when they had the option.
