Still working on finishing the basement, I hate it but it has to be done. I did just order the ARP head stud kit so I can secure the heads to the block. Looking into the right push rod kit, MRL suggests I get 3/8" rods with 5/16" ball and cup ends. Comp Cams makes some semi finished push rods in that configuration, that just need to be cut fit and then the cup pressed in.
