Valve seals...Intake and Exhaust Different?
I just changed my valve seals and noticed some are brown and some are black...did some research after the job was done and saw they have a difference in exhaust and intake...do i need to change them?

Brown is for exhaust if I recall.
The rubber is a different material supposedly. Designed for the higher heat that a exhaust valve would maintain in operation. A lot of aftermarket seals don't differentiated but whether that means that all of them use the higher temp rubber or not is not stated.
I'd pull em and place them correctly for ease of mind myself.

The above is correct, GM is different colors, most others are not. I would not go back and change them unless an issue popped up like smoke on startup or something like that.

I have comp cam valve seals and they are different colors, I think i might just leave them until smoke issue does occur...it will be just as much work now than later and i installed the same seals on my camaro not knowing about them being different and never had a problem.
