318 Build.. Zero Deck or Stock Deck Clearance?

He asked about compression, so I answered that he is at the compression already that will be challenged by todays gas. In other words, he doesn't need to "deck" the block to gain compression, IF all he is after is compression. His compression with those heads and pistons will be more than adequate for a street engine, no matter if his pistons end up .010 in the hole, or .040 in the hole.
AND...... AND..... the compression will be more than sufficient to perform.
