2.0-2.3L type 4 engine, my journey to enlightenment, Or why the F can't I just drive my car! Options

I have been working on my 914 for almost 20 years now and have never actually posted info about it. I have read and re-read on this and various other versions of this forum for a long long time and figured it was time to step from the dark dankness of the internet shadows and actually contribute some (also I have questions that remain unanswered, so lots of selfish motivation still abounds).

And now I have to be honest and say I have neglected the poor thing for the past 6 years. It has been sitting patiently waiting for me to finally finish my PhD, get married, and medicate my boundless ADD, most of which has now been accomplished!

I am hoping with a little encouragement and advice I can stay on track and get this thing done over the next few months, barring any ridiculous life crap (which always comes along).

So what are my hopes and dreams?
-2260cc engine
-Megasquirt
-fun times

Thats it! I really feel like that should be easy right? HA!

Look, I get it, I have been cheating on you 914world. You saw me with another car, it's true, but I sold the BMW. You have always been the only one I truely care about.

To coax you back in, pictures!

The first thing my aging brain did was ask:
"what the hell lifters are these?"

So I called webcam to see if they could help me identify them, and sure enough they are not theirs. So I ordered a set of Webcam solid lifters as I have seen/heard of plenty of horror stories about cams eating themselves when the improper lifter cam combo and oil is used.

And for posterities sake:
Scat 20011 Springs next to a stock spring
(IMG:http://www.914world.com/bbs2/uploads_offsite/www.patsachs.com-7353-1617896826.3.jpeg)

I measure out the Scat springs to be around 2.32" total length and an ID of around 0.931"

The guide boss is around 0.924" so the fit is certainly snug:

But they fit. At first my installed height was around 1.45", but a few "seating taps" with my hammer got it to around 1.48" so I am getting to a more acceptable level.

Next I noticed that my stock keepers were nice and shiny at the mating surface, where as my brand new ones looked like someone finished the edge with a chisel *sigh*.

So over to the only reason I agreed to redo my kitchen countertops: an ultra flat sanding surface!!

And a few strokes later:

Nice and shiny and smooth (stock keeper is on the right, new one on the left)

With this done the keepers no longer "rocked" when placed on the stem of the valves and when I installed them, I am now at 1.5" of installed height! Yay!

This should give me a seat pressure of around 140 PSI

And my clearance from coil bind should be around 0.1" with a hypothetical nose pressure of around 220 PSI. I am still on the fence about if this is enough for the webcam 86B. In conversation with webcam, they said it is in the middle between their double and single springs. I have no intentions of running this thing above 6000 RPM, so that is where I am at. Should I run what I brought? Should I go double spring? I could also go "beehive", but both would likely require machining.
