I have seen a 440 block that a machinist's straight edge rocked on #3 saddle. Yes they did spray paint the saddles and bored to just wiping the paint off. But when done the timing chain was sloppy. It went into a motorhome. It was not one of my builds, I had no pony in that show. The motorhome owner demanded they just put it together as is. Shop foreman said no and Owner took it somewhere else. #3 bearing was thru the copper and on the steel before align bore/hone. Crank did clean up at 0.040" but still showed shadow marks.
I would have scraped the whole engine. It had been over heated so many times.
The foreman said he thought #3 was the only one that was true deck height. That block had major core shift well before all the overheat cycles that warped other stuff out of spec.
I was a US ARMY SP4 and worked part time at this NAPA machine shop @ $0.95 an hour. My job was to knock down the long blocks, box and tag everything. I had to straight edge most surfaces and chart them. Just about everything on this engine was red tagged.
