Massey Ferguson 35 23c engine rebuild

[Sam1959]

The head gasket failed on my 1959 4 cylinder 35 and has forced me to rebuild the engine. The cylinder head is away having new valves seated, guides etc. I have heard that increasing the size of the precombustion chambers on the head slightly can increase starting performance. I can't find any details to do with this procedure and was wondering if anyone has any information about it. Is it worth doing?
Thanks
Sam

Perhaps you should consider having the head modified to take glow plugs

A die grinder with a tungsten carbide burr and a gentle touch, will do the job easily.....
