Thanks for your input every one, I have checked the head & block and all is flat and good. The pistons have flat heads and the cylinder head has plenty of clearance, the sparking is over the valves so no problem there either. Maybe the theory of using other fuel maybe the reason, pretty sure the guy who did the restoration didn't take the head off as the compression was good but I will ask him. Have only one port to clean up, bit of corrosion due to water getting past a loose plug on no 4.
