Average prices for port work around here seem to be $300 for port match and bowl cleanup and around a thousand smackers for a full on port job. That's if you can find someone you trust. Add on the initial cost of the bare castings and another $650 for valve job, new guides, hardened seats, new ss valves and another $100 for a good set of springs and anyone can add it up for themselves. Those out of the box Eheads start looking pretty good for $2200 + another $125 for bolts.
