I already have a set of these 2.05 valves and want to know how much additional cost is involved over using a standard 2.00 in a stock head? Since I already have these valves I figure it might be the same or a little more vs. buying 2.00 and having them installed??

 

If the guides are good, then it would be $150 to install oversize hard seats, and $250 for the valve job(cleaning, shoot seats, cut valves, setup spring heights, etc) Surfacing should be done too, at $100

California prices are more expensive than elsewhere...
