Message: [QUOTE="kleake, post: 1399563, member: 25987"] Spoke with 2 shops and 2 machine shops. None have seen this issue, but all seem to agree it's likely the heads were not machined correctly and the valve stem height it too high. "IF" this is the case, Ford only covers up to $150 of labor. hahahaha Yea, that was my thought too. I am going to pull a valve spring tonight and measure the valve stem height to verify, but I can't find the specs anywhere. Does anyone know the specs of what they should be? Also, if that is the case, all agree that taking a little off the tops of the bridges should be an easy solution rather than pulling the heads. If I can get that spec, and if I can get a valve spring off with my compressor i'll know for sure. [/QUOTE]
