I'm going to replace the intake retainers and keepers with AP2. Question: While I've got the the cams and rollers off, are there any other parts to replace for good measure? Springs, any seals? My engine has 53K miles on it now. I'll be FI by summer.
Thanks
Thanks

The left one is flat (seen from left to right)
The right one is curved-up at the outer-edges.

I don't think you'd easily be able to tell if the retainer was flat if you were inspecting them while they were in the car.

Actually, I thought we were looking at the sunken keeper and also the fact that the tip of the valve stem sits lower with respect to the retainer on the bad one.

Look at the keepers on the right; They are obviously sitting lower in the retainer than is the case on the left.

Look carefully at the cotters (the two half-circle shaped parts that hold the stem and keeper together). In the good one the cotters are high up, but in the bad one they have sunk down into the keeper. That's what you are looking for.

Thanks guys, I see it now.
I presume it's very difficult to tell without taking them out?

Yes, you are right and the other "answer" was incorrect.

But, that's definitely not as easily identifiable as the other symptoms.
