Also make sure you get a new head gasket.
Thanks. I had thought of some type of test like this but was not positive how I was going to test it. This makes the most sense. Any suggestions on what liquid to use?Tilt one side up (i.e. exhaust side) and pour solvent into the port. If the valves are leaking, the solvent will run out. Do it for the intake side also.
No leakage, valves are good.
I replaced mine. After I found out what the total torque was on them I would not do it again. I don't believe that they are stretched all that much to the point of needing replacement.The service manual doesn't call for replacing the bolts when reinstalling the head. Just says clean with a nylon brush and blow out the bolt holes.
As far as going with studs, I wouldn't worry about it. I'd just stick with bolts.
Thanks. Thoughts on the brand for the bolts?My reading comprehension is a fail this early. It does call for new bolts. Main head bolts are 22 ft-lbs + 155 degrees and the four front bolts are 26 ft-lbs.
You know - I was surprised when I found out out the LS engines are the same way. Most of the builders I've talked to are VERY adamant about using new head bolts. Stock type sets are not too expensive, so I guess it's cheap insurance...I just can't image the stretch on steel bolts when bolting them to cast aluminum. There better be a lot of thread in the block.
