My stock engine has 50 lbs on each cylinder and has good power. .0025" is borderline on what you should do. If you do short local drives, you'll probably get by OK for quite a while. If you want to put on lots of miles and go on trips, it would be best to have new babbit and shims.
BTW with .003" clearance on a newer Ford V8 I can hear the rods.
