Craftsmanship isn't there

Summit RacingSummit Racing Verified Purchase

Ordered this block to replace a dead boat engine. Once I received the block I took it to my machinist for piston fit & finish. The bores are oval shaped. front-to-back have .003 clearance & top-to-bottom has .001. I'm stuck using it. Also, oil galley plugs are not installed.
