I have a question about which Holley pan will be even with or above the engine crossmember? 302-2 or 302-3 ... what would be the main differences in the pans?

I also notice the recommended bolt kit for the engine mounts 71223015HKR says they are 150mm long and the recommended bolts according to the instructions are 140mm long. which is correct?
