So, this is the first overhead valve engine I've taken the head off of. Dang, it's so heavy! I've worked on flatheads before only, and mostly tiny ones, like the Model T engine.

I'm working on the 235 in my bus here, and I was both amazed to see that the intake valves were so darn big, and to see this weird junk stuck on the exhaust valves. I've only ever seen carbon before. This stuff is a funny colour, and it seems even harder than carbon. There were also deposits like this in the combustion chambers, and on top of the pistons. In fact, in some places, it was 1/16" think, and even more tan-ish-ly-white than on this valve.

This engine sat for many years before I woke it up. I have put about 2000 miles on it in the last few months.

Thanks for any info.
