Wait a second! You can replace the valve seats in an MGB head??? If so, my
machine shop gave me some wrong information...I gave them a 'B head for
magnafluxing three years ago, and they told me it was kaput because the
valve seats were cracked! Can anyone tell me if this is true (it must be,
he's got a good head!) If this is possible, I might have a good head lying
around...
