TDR Billet Girdle Cylinder Head. This head was designed to cool better than others on the market by moving all the water around the cylinder.  This head was designed to cool better than others on the market by moving all the water around the cylinder, not straight acrossed the head.  It cools the cylinder walls to keep the friction down and also allows more heat to get the combustion chamber hot enough to have a complete burn.   Includes 4 outside studs that connect to the crankcase to help control head gasket blowby. There are NO removable domes. This increases it ability to seal better. Part#21-5722
