If not your good! If it does leak, to find a crack you will probably have to have it magna-fluxed. Any engine machine shop can do that. If you are planning to use the block, it isn't a bad idea to get it magna-fluxed anyway.

Its going to be a pulling tractor engine. Just dont want to sink money into it and have that be a week spot
