14mm rotor head install

[cummins12club]

I'm bout to buy a 14mm rotor head here soon from Rocken teck and was wanting some input of doing the install myself I am pretty fimilar w the ve pump no expert by any means but I've done everything to it currently myself, anyhow I have an old 89 pump I use for practice and have taken the rotor head off to see what I'm getting into before I attempt to do my actual pump it seems to be if I remember correctly their are 2 springs and a tiny washer/shim thing I have to be mindful of other then that is it truly that easy of an install just 5 torks bolts? Any tips on what I need to do or what not to do would be great, I realize the pump will have to come off and I am curious is to exactly how I should go about doing that as well so I don't screw up the timing
