I heard some guys use exhaust valve seals for both their intake valve
seals and exhaust because they withstand higher temps. True or BS?
I'd like to know before I get my head rebuilt.

 

never heard it. Just buy whats intended. For valve seals just remember to go OEM

 

arent they all the same?

 

there all the same genius

 

no they are not the same, the exhaust valve seals are smaller, the machine shop mines in backwards, intake in exhaust and exhaust in intake, and I was having smoke comming out my valve cover, switched them and the problem fixed

 

ones i got for my sohc were all the same

 

its strange, I bought honda genuine seals, and they came with 2 different shades, plus on the intake seal it say in, and the exhaust ex. then I replaced them with KMS seals and they where also different types, and now I have a few set from felpro gasket sets and the felpro ones are all the same but its for a LS, maybe the b16 ones are the only ones that are different.
