you get the BRAKE
How could you possibly get a GOOD look at the valve stems, or the guides without removing them? And the only way to tell if those valves are not "burned", is to remove them from their guides and clean them thoroughly than inspect and measure. Just because you see carbon composite buildup doesn't mean that carbon buildup is the only problem. But for your price, I say its reasonable if someone was looking to machine. I am looking for another head actually, but I have too much cash tied into my bottom end right now.
