Valve Drive update

[Tony Hoffman]

You have a good plan there, and will find it's the intake valves that are
bent. If they hit hard (as in significantly bent) I'd highly recomend
replacing the lifters associated with them as well. Was bit once by that
(lamm crack inside the lifter that couldn't be seen until disassembled).
Never again.

The replacement of the valves is not that dificult of a job to do, but you
do need the tools to do it. Unless you rent them, I'd suspect just
purchasing them will exceed the cost of the head rebuild. Should be in the
$300-350 range including surfacing, at least that's the going rate around
here.
