The smaller ones go in the smaller holes.
Not sure what you need here.

Sorry was tired last night the heads are still bolted on and to try and clear up my question I'm looking for what order the valves are in

Exhaust valves are above the exhaust ports - the others are Intake!
I believe they are in this order; EIIEEIIE
I think the firing order is the same as Chevy: 18436572
Can't think of anything else you'd be describing - - -

Shouldn't that be E-I-E-I-O ??

Well this explains why my last valve job was a complete failure...

Is it necessary to install the valves in their exact places? (Like #1 intake cannot go in #2 intake's position.) I thought I heard that before, but the accuracy is questionable. Maybe I am thinking about cam contact parts...


...and on that farm he had a pig...

Well, the Oldsmobile valves rotate, so they wear perfectly evenly all the way around.

It's a good idea to keep them in order.
