Looking at it from the front of the engine bay, is the first valve on either side an intake valve or an exhaust valve? And they would continure in order moving back right, like intake exhaust, intake exhuast... or the other way arounf

 

When looking at the motor the exhaust valve will match up to the exhaust port on the head
it goes from front to back on both sides.

Exhaust 1
Intake 1
intake 3
Exhaust 3
exhaust 5
intake 5
intake 7
exhaust 7

 

And the left side would match up the same?

Exhaust 2
Intake 2
Exhaust 4
Intake 4
and so on?

 

like he said, ur your header/manifold "tube" matches up to the exhaust valve.
8 cylinders, 4 exhaust tubes. the other 4 are intakes.

 

8 cylinders, 8 exhaust ports, 8 intake ports; 4 of each on each side of the engine.

 

I think you missed the point of chevy1963's post.

 

Funny how they put the exhaust valve right next to the exhaust port..

 

Got it figured out. I got Chevy's post there, but thanks for noticing Shoebacca, just mistyped it. One look at it and I figured it out, should have been able to figure that one out on my own, though, doh
