You are gonna run 440-1 heads. Are you going to use the ports on top at the rear of the block for the oil lines? I have a World / 440-1 for my 540 and after seeing the Indy set-up for oiling the heads (flimsey) I made a pair of AN-4 lines and put pipe plugs under each of them after I opened up the threads and reduced the height of the plugs. In each plug I have 0.060 dia holes. A set of 0.090 plugs are waiting if I need more oil to the heads. They can be changed with the engine bolted to the tranny.
