If you mean"Reverse Flow Head" then you have a head, or more specifically, a car that is designed to rout the coolant to the head first, then to the block. This keeps the aluminum head cooler and is more efficient.

Reverse flow cooling (which will NOT work on just any old engine, typically found on LT-1's) was designed to flow the coolant through the heads first keeping the combustion chamber cooler, thus resulting in increased H.P.

Reverse flow systems pressurize the cylinder heads and bleed off through the block. Coolant gains only 1-2 F as it goes through the block. Reverse flow decreases the temperature of the coolant through the cylinder heads by this amount. The fact that steam rises complicates reverse flow systems and generally makes the 1-2 F reduction in coolant temperature insignificant at best.
