We knew ahead of time that it had a miss, but it made it to Utah and back, towing another Crew Cab on the return trip. Found out tonight that #6 exhaust valve had no seat left, and the valve guide was HUGELY worn out. #2 valve seat was starting to go as well. The shortblock was all fine... bored .040 over and everything looked in order. Just one head needs to be completely gone through... meaning do both heads, meaning time and money. So now this weekend, I get to yank another 454 I have and bring it back to town and I'll give him that one. Funny too, cause I was JUST going to get that motor running this weekend after sitting 2 years... now after waiting that long I'm yanking it.
