I am putting this 1928 chevy head on my 30 ford flathead four engine to give it a shot in the arm. This old 40 horse pig might make 100 hp or more with this old bowtie wonder. The alloy plate is an adapter to mate it to the ford engine. You toss the ford valves and slide pushrods in the holes to actuate the chevy valves. This is what I play with when I am not spending money on my V.
