I just went through a similar situation when I put aluminum heads on my .060 over 440. Tried the factory replacement fel pro and the 1009 fel pro gaskets and BOTH overhang into the .060 over cylinders. Even though they say they fit up to a 4.400 bore, the fire rings were hanging in the cylinders at 4.380 bore. The fel pro marine gaskets are what you need to fit your .060 over bore. Also had the bottoming out issue with ARP bolts. The middle row of bolts were not seating on the head when torqued.
