New camshaft install questions

HI, I'm building my first Mopar engine, a 340. I'm not sure about a couple of things, hope someone has more knowledge. First the specs: it is a CC (Comp cams), high lift hydraulic cam. Grind/Part # XE275HL -10. The Gross valve lift (both intake and Exh) is 0.525, Lobe Separation 110, Duration @ .06 and 0.050 = 275 /287 and 231 /237

First question is about what it says on the Specs card: It says "These specs are for the cam installed @ 106.0 degrees intake centre line"

But do I need to do anything special to make it 106 degrees? Or will it be automatically done at 106 if I just put it in with the cam sprocket timing mark lined up at TDC with the crank mark ? Or does it mean I have to buy a degree wheel and "dial it in"

SECOND question: I want to run light valve springs initially to avoid wiping a lobe on initial run-in as this is the most critical time for a cam. The valve springs recommended by CC for this cam are dual springs + a damper so they are pretty heavy. Is it ok to use worn original OEM springs (used 45 year ones from a 318) or do I need more pressure on the lobes to effectively run it in? Someone told me to pull the inner spring and damper out and run it with them initially, but I still think they might be too heavy to risk it.

Thanks
