Poor engine never got broke in! Never run over 3k? Never worked? Never anything but synthetic? How many miles does it have?
I have pushed mine so hard and far that it should have blown many times if it weren't built so tough. Yeah, it's wimpy, but it just keeps on going. Have to tow and hit redline a few times on these work horses. Keeps them healthy. Who lives longer? A guy who lifts weights and runs once a week or a guy who never leaves the house and just sits on the couch?

Don't bother doing anything with the stock heads, just replace them. Get NEW castings. They are thicker, and less prone to cracking. (like the stockers do...) You can pick up a pair, ready to bolt on, for around 600 bucks. Or, if you are feeling froggy, you can even upgrade to the EQ heads....... Either way, just scrap the stock heads.
Do you have a link for them?

Well I checked with three different shops today, and they all told me that if I bolt on new heads and valves, I will probably throw a rod or burn oil excessively afterwards. They all said the heads are notorious for cracking, and they said I should just find a lower mileage engine and drop it in. Seems odd that three bad exhaust valves could wipe out an otherwise a good running engine.......
Now I'm really confused. Seems odd that three bad exhaust valves could wipe out an otherwise good running engine.......
