If the heads are worth it, I have to agree with this.
Of course the guide job is going to flow over into the valves being redone, so take that into account on your total cost.
Damn, it's second nature to me, so I just ASSumed everyone would understand once you replace the guides you MUST do a valve job. Which adds to the cost. Then there is the potential that you don't have hard seats and those should go in after the guides.
