Meticulous Mouse For The Mule
Since this head was designed with big ports that have as few turns as possible, many components end up on top of each other--like the center head studs between the two middle cylinders. The only way to access these is to trim the valvespring seat buckets with a grinder--far away from the engine, of course! (NOTE: Every time Urban grinds or machines something, it is thoroughly cleaned before being brought back into the engine assembly area.)
