LT 4 Heads

[wx briefer]

I would not be too concerned. I have seen other typographical errors find their way into subsequent publications before. This may indeed be such the case with this. In any case, if there exists any difference between whatever head castings, there is certainly not enough information to determine which is better and for what reasons. I never allow any judgement to be formed by one voice. Must be mighty obscure info since the engine has been on the road for 8 years now.

Let's see, Corvette Mike, The Black Book, Chevrolet bulletin, yeah I guess that's one voice, I'm sure they don't know squat....
Call your dealer, run your VIN, go up to the Chevrolet owners site, run your VIN, if you had the problem it would have ruined the motor by now...this is a dead horse

Anyone else here remember the classic exclamation made by the Warden in that old movie, "What we have here is a failure to communicate!" ?
