4 corner water?

A crossover with a bleeder will allow you to purge air from the rear of the heads when filling the system. (a definate plus). Plumbing from the rear of the manifold to the t-stat area or the water pump will circulate coolant from the rear of the heads; a superior design to O.E. We have used this method to solve cooling problems in supercharged street engines at my shop for many years. For drag racing I think careful purging of air pockets from the cooling system is more than adequate for most apps but if you want to idle your 600 C.I. 14/71 blown BBC thru the parade route for a couple of hours in 100 degree temps with the A.C. on (so the tootsie in shotgun is comfy) you will need to use the alternate method.
