Going to play lotto 440

I will taking the motor apart this afternoon so I will be able to check the heads that are mounted right now. What should I do to the block and bottom end before installing? I can always upgrade heads and intake later with engine in car. Just want to get it going without breaking the bank. Would like to put efi on later. Fitech kit. Gonna pull slant six this weekend if I get the time. Thanks for all the replies. I will let you guys know what I find tonight.
