Just did not want to take a chance. I did not see the engine run or see the donor vehicle. The guy I bought it from seemed truthful but had no proof of mileage or condition of engine. Was going to just take the intake, exhaust manifolds and spark plugs out. When I found a little rust on the intake valves (1), must have been just from sitting. Everything else looks great. Got $400.00 in all the gaskets, ARP studs, spark plugs and belt. Also bought a "How to rebuild an LS series engine". I have built many engines, but not like the GM LS engine. When I was searching for torque and sequence for the heads I learned they are a little different than what I am use too. But I feel good now knowing the shape of the engine. The knock sensor harness looks OK do I need to replace any way?
