So guys I need some more advice.
In my last post I was working on the passenger side head. I wire brushed and lapped the valves. I also replaced the valve seals. The exhaust side were tough to remove but the intake side came out very easy. I reinstalled the valves which took sometime due to the keepers. Two of them popped out and were almost impossible to find. Everyone warned me of that but until you actually install them you don't realize what it takes to make them pop out. Once all the valves were completed, I installed the spark plugs and turned the head upside down. I poured water into the combustion chamber just to see if any water leaked into the intake or exhaust ports.
Last night I started working on the driver's side head. The exhaust valves appear to have more carbon on them as compared to the passenger's side. I also noticed that they are a bit narrower or worn right under the chromed part of the stem. I also noticed that there is some really tough carbon on some of the exhaust valves right below the area that rests on the seat. Whereas the passenger side exhaust valves didn't appear to have that.
How could one head look so different than the other?
Even the piston tops on the driver's side have more build up. Makes me wonder if the driver's side head sees much different temperatures than the passenger side.
Anyway, here are some pictures of the exhaust valves from the driver's side. They have been cleaned up similar to what I did on the passenger side.
Is there a noticeable issue with the exhaust valves?
Do I keep with the plan of lapping the valves, changing seals and resurfacing them?
Let's face it, pouring water to test for leaks does not guarantee that they will not leak air. Also, what if I get some seepage using the water technique after lapping them?
