Stock valve guide size X heads

Your 340 DID NOT come from the factory with 11/32 valve stems.
You are an idiot.
I'm sorry but I
did not realize that we had a history. And as far as that goes I could care less if I'm on your ignore list. I have forgotten more Mopar than you will ever know.

Now excuse me I have to go get my fishing rod ready to travel.
Im glad you called him an idiot...there are people on here commenting on 340s that have never been in the same room with one...:)
