Machining a block, how it´s going???

The core block I just got has forged Venolias in it with no oversizew noted. Seller said it was .060 over and junk. I have a sonic tester so big doesnt mean junk all the time if it's cheap enough... Then I measured it. It's only .020 over right now. You never know... piston makers can do whatever. I Just ordered a set of std bore 340 pistons for the 410 I'm building... Because a .040 over 360 is the same as a std bore 340 with the 4" stroke...lol And that block is rough bored and waiting for the pistons to come in for final honing and square decking.
