I wasn't telling him to do that. It was more to make the point that you can grind the valve guides down abit on the intake side whereas you should never grind the valve guides on the exhaust side. It was just a piece of advice because I have seen that some tuners actually grind the valve guide on the exhaust side as well.

The relatively easy stuff like matching the manifolds to the head and possibly cleaning up the ports abit (not opening them up but smoothing casting flash) should be achieved without any troubles.
