Ummm, guys, the H22 motors are Nikasil coated; therefore, if you take the motor to a regular machine shop that offers normal horning, you are asking for trouble. Besides taking the block to a shop that's capable of offering Nikasil coating, the only other alternative is to get the block sleeved. We are able to offer the sleeving if you are interested, but if you have any questions, you are more then welcome to give us a call.
