I'd say it's a little steep.

I had the Rome, GA price me all the parts needed (minus the gallon of coolant) and they came up with about $225.

I'd gladly give an experienced Honda tech 4 hours to do this at $70 per hour, so my estimate would be around $500.

You need to make sure they also replace all the seals included in the kit (mainly the front crankshaft seal). They will also replace the balancer belt, water pump, intake gasket, power steering belt, drive belt and coolant as noted.

This would also be a great time to have them check and adjust the valves since they will have the engine starting at TDC and the valve cover off.

I'd try to negotiate with the service depart for $650 with the valve adjustment.
