i paid to have my p's assembled after having them milled. I used the trickflow springs which i got cheap but without the retainers. the shop used dif retainers on the intake side an swapped the exhaust ones over to the intake side go get the spring height right.

It's ok if the umbrella seal moves with the valve, it's supposed to. I prefer the teflon ones though, they work better and will be more out of the way when you are installing the valve springs.
