Rockers and Valve Springs

Rockers and Valve Springs
I'm going to replace the Rocker Box Gaskets on the old EVO and am also considering Rocker Lockers, Rockout Lockers, or the 8/32 Set Screw fix. Plus maybe changing the Valve Springs.
So let me explain. The Rocker fix is a choice between the above mentioned products and I'm looking for advice on which way to go. The drilled and tapped set screw idea appeals to me but would like to hear pros and cons. Also, would I need to be concerned about Rocker Arm end play and maybe using a cutter and shim?
Next is the Valve Springs. The current springs are high lift, and I think 175 lb tension which I'm afraid is overkill and just worrying me. The cam is an Andrew's EV3 which is 0.495 lift and will work with stock springs. So I'm told. Do I really need to worry about longevity with what's in there?
So can I remove the Valve Springs with the heads on using only the compressed air and maybe some fabricated lever type tool vs the Nub or Goodson (?) Tools? Anyone done this? I've removed springs on the bench before with a big clamp and I've seen some pretty tricky things done with a socket and even zip ties.
Lastly, I lost my stock Valve Springs and would need to buy some used takeouts. (Broke Biker, what can I say?) I know they're out there. Anybody? Donations accepted!

Rocker Lockers; no drilling, tapping, etc.; simple install and they work.
Not an expert on spring pressures but 175psi on the seat does seem like overkill. With that cam, I think OEM beehives springs, '05 up would work well and accommodate higher lift cams in the future. Never used the Goodson tool but have read good things. The only issue I have read is the fitment of the tool over the sping retainer; apparently some aftermarket retainers are too large to accommodate the tool.

currently. I'd like to save my money for my bike since I ride it. I'll be getting a set of your lifters for it of these days.
