Junkyard 5.9L Magnum + Edelbrock LA heads build

I hear you, all valid concerns. Well in that case I'd be concerned about getting the correct crosshatch pattern, I don't want to ruin my cylinders if they're already in say, 90% good shape? And stripping the block and hauling to my machinist sounds like a pain just to get a hone. HOWEVER... my machinist (actually it's a team of 2) is a badass and can probably take one glance at my block and tell me how it looks and if it needs anything. These guys are used to building 1500-hp BBC drag engines and crazy giant-turbo LS monsters so I trust them for a moderate street SBM build.
And they probably have a nice bore gauge that they can set to 4.000" and know in a minute of running it up and down the bores what you have...

I've done the no-bore thing before a coupla times....when in college, workgin part-time, racing, and limited on $$, on bores probably worn considerably more than yours, and the results were pretty poor/irregular cylinder sealing. I just don't feel anymore that it is any real cost savings long term.
