Billet head kit for the 1991-1995 550SX aluminum reed cylinder engine.  Domes are machined to a 76mm bore diameter with zero squish relief machined into the dome.  Head design is all orings and does not use a head gasket.  The head is designed to be installed with the water outlets on the intake side and has 3 water outlets available.  Head kit includes domes, orings, and brass water fittings and plugs.  This head uses the stock studs and nuts.

Compression readings are based on a stock cylinder taken at sea level.

This will NOT fit the 550 cast iron piston port cylinders.
