I would have the machine shop check the main bore sizes with a dial bore gauge and straight edge to see if the block is straight and true. Somehow hen the block is line honed it causes timing chain fitment issues. You can get undersized sets to compensate for that but can be a pain. In all my years of racing I have only had one block line honed. That was after I broke a crankshaft. That block was never right after that. Ended up scrapping it.
