I'd have the crank turned and polished,new cam bearings installed,definetly plastigauge everything,new balancer,water pump,rings,proper bearings,and gaskets. I just bought a std re ring/overhaul kit with proper sized bearings for the crank when I did mine years ago. It's ran well and has high oil pressure and doesn't use a drop of oil inbetween changes. Machine shop did the cam bearings,crank work,hot tank and magnafluxed the block. I did set the bearings on the tight side of clearance. Has about 75# press on cold start and 60 when warm.
