I bought a P72 head fresh from a machine shop off ebay. I got the head and i put it away for about a month until i was ready to slap it on. Now im about to port it and I notice that the valve stem seals are mixed up.

They put some black spring seals and white spring seals on the intake, same deal with the exhaust side. Im pretty sure it should be all black spring seals on the exhaust and all white spring on the intake. However the seals look EXACTLY the same but why would honda label them differently?

Let me know.

 

They are different for intake or exhaust. I would go ahead and put brand new seals if they aren't new.

 

i would change them asap. they are color coded for which side it should be put on. one can withstand more temp then other

 

so does black spring go on the exhaust sude?
