Exhaust bolt pattern- CHI heads

There was some discussion about the bolt pattern for the 2V & 4V heads and how they compare to the CHI heads. Here are som pictures.

Last picture is the 4V gasket on a CHI 218-3V head.

Looks like that gasket set would need to be cut away around the top bolt. A lip sticking out into the exhaust stream would be bad. Especially around the roof of the port.
