well ive pretty much got it narrowed down to XE-R lobes but i don't see the need for the reverse split design you suggested. i thought those were for cars with a better flowing intake than exhaust system?

That is not reverse split. It is 226° Intake 230° Exhaust. That is traditional split.
If you don't need a split at all, go with a 226° or 228° straight cam on a 110° +2°.

Spring life on the new Patriot Gold Extreme springs should be a lot better than 10K miles. I wouldn't even bother checking untill 20K. If you are still uncomfortable, get one of the similar XE-R cams and use the Patriot Gold springs.

I would keep it on a XE-R exhaust lobe, like this:
227/232, .639/.595 110+2 LSA

Best of both worlds involves flycutting to clear the cam with the VE's you want, then getting the gasket that gives the quench you want, then getting the combustion chamber the size required for the DCR you want when it is all said and done.
