BMW s54 cylinderhead from Hack Engineering MachineShop

As seen above a BMW S54 cylinderhead, we see these on a regular occasion and we have built many of these in house ranging from standard road engines right the way up to fully forged, forced induction, big HP monsters.

A full strip down and ultrasonic clean are followed by a pressure test to check that the cylinderhead is in good shape. if required we will then reface the head using either a PCD OR CBN cutter. Following this all valve and guide measurements are taken and the cylinderhead is built  back up to its former glory.
