I've said my peace. I think that the spec is fine, and I advise you adhere to it. I will reiterate and say that I think the middle of the spec is what you should shoot for. I can state my reasons in a long winded explanation, but I don't want to type that much.
Here's my question to the OP:
IF you do decide to throw the recommended limit out the door, and go by someone's opinion, are you willing to gamble your dollars that it is correct? If it scores the piston, are you going to quietly tear it back down, bore it again and rebuild it and pay the cost? Or are you going to say
"Well some guy on the internet said I could!" or go back to the machine shop and say
"It's all your fault!" and demand that they pay for it? Are you willing to take the risk....??????
I think if you do, that's just silly.
