Re: replacing valve stem seals

Orange is generally High temperature so would be for the exhaust

Other way round. Brown ones are for the intakes and the black ones for the exhausts. I used them on my stroker.
You'll need to remove the valve springs to install the new seals so make sure the valves don't fall into the cylinders, or else you'll have to remove the head to retrieve them. To avoid that, just make sure the piston is at TDC on the cylinder that you're working on.

Remove rockers, then use air to presurize the cylinder thru the spark plug hole, it will keep the valves closed once the rockers are off. Most REAL parts stores should have the spark plug adapter as well as any of the tool trucks...

Either way, if you call Napa they should be able to look in the catalogue or computer and tell you which are for the intake and which are for the exhaust based on the part numbers.

Re: replacing valve stem seals

I got some new valve stem seals and was confused for a bit until I took a good close look at them. One set had a veery small "IN" printed (molded) on them. The others had a very small "EX" molded on them. Unfortunately I didn't by the same brand so I can't help you with part numbers.
