High Compression Head

[nkaminar]

A shaved head will work just fine as long as you recut the piston clearance and check to make sure the valves will not hit. You have to take a lot off so you may get into the water jacket. I had a shaved head on my Model T which worked quite nicely. It was a "low head" to begin with so the compression ratio was fairly high. Quite a lot was taken off, over half an inch, so it was into the water jacket in places, but the head gasket sealed off those areas. I had to use shorter head bolts.
