It's cool, no doubt. You need to make (by cutting) a headgasket or purchace one from Falconer. Exhaust and intake is the same story. The block deck needs to be redrilled and tapped to the new bolt pattern, most go into the water jacket, so sealing is nessesary. The sideplate (which must be fabricated)is a bear to keep sealed as well. Lots of fun but lots of work as well. Goes real good! Arm
