I don't but I learned to make sure the block deck and head surfaces are very smooth before using them, don't ask me how I know Make sure and get the RA numbers(measured surface finish numbers ) and use them on the finish on your heads and block to make sure the gaskets seal properly
i ruined a fresh build do to a water leak that wasnt noticed and the car sat for awhile with water in the cylenders,had the block resurfaced and no more probs.
