hey all,

just wondering how far can a head be 'gone' before you
cant skim it anymore??
The head appears to bow in the middle !
(2ltr Zetec head)

i've had it measured and was told that it was 14 thou out
(if i remember right)
is that too far gone? i heard Zetec heads are supposed to bow
between the middle two cylinders??


any help would be great thanks.
