I deck all blocks to zero or near zero depending on numbers. I feel after spending as much money as I have already spent the cost of decking is such a small percentage of build it is right thing to do. Benifits are many and include proper relation to crank / cam center line, proper seal surface, ability to correct any core shifting and allows CC of chambers ( deck runout is big influence), performance adder etc.. If only decking to zero you will not alter intake to head seal or any other spec with stock stroke and pin height. Only down side is cost and that is small % to insure many possible conflicts removed.
If just a cheapest build possible maybe overkill but is that what you are doing or are you upgrading parts and performance?
