'68 318 - Coolant left in heads when removed.

if you want some more coolant out of the block before reassembly roll a piece of paper shop towel into a length and poke one end into the coolant in the block, letting the other end hang down outside the block. capillary/syphon action will draw the coolant along the paper and it'll drip off of the end hanging down. it'll drain like that until the end inside no longer is in any coolant. now the had gasket face can be dried and cleaned for reassembly.
