All you have to do is correctly answer, what is this head for.


Thank you. I am wondering, though, how come the four valves are so
close. I cannot imagine cylinder placement that would fit these
valves. For a diesel, we need 2 valves per cylinder, intake and
exhaust. If so, how could the cylinders be placed?

It's likely that two valves are intake and two are exhaust serving a single
cylinder, just like many modern gas engines.

I have a question though. If you don't know what this is from, how are you
going to determine who gets it right?
