Finally the decision has been made.

I do have a question about the original seals are they supposed to stay locked down on the guides or do they move up and down with the valve? Cause I noticed during disassembly that some was locked down tight as could be on the guide and others where up on the valve towards the retainer

Perfectly normal either way. Now with the Viton or the Teflon seals, they stay located on the guides.
