just one more vote to run it. it WILL be fine. a little noisy on start up (i like that sound, it's very comforting. you know you have forged pistons). just don't beat it when it's cold (you shouldn't anyway). i've run more than that in street engines. "it'll be noisy! it'll burn oil! you'll have sealing issues! ring life will be compromised!" none of the above were encountered. in a previous life i had a 340 duster with near .009 clearance, and it was noisy when cold, and you could hear them all the time, but that was one tight little screamer. i put a lot of miles on it, and it saw over 7,000 rpm daily. well over. and i gave it a little squirt of nitrous (this in the 70's when nitrous was scary and friends were blowing their stuff up using it). i put 45,000 miles on that engine before selling it, and leak down was still less than 3% all 8 holes. no freshen up. it went to Minnesota to run in a real race car.
