I went with an Isky Hydraulic Flat tappet cam.  .542" valve lift. 270 adv duration. 221 duration @ .050" Ground on a 108 lobe center.

I use Valvoline VR 20W-50 oil so I don't have to worry about adding separate Zinc additives for the cam.

You will probably get different opinions on the cam choice, but I love the sound of my engine and performance has been good.  My engine builder is old school so this was part of his recommendation.  I have no regrets, but this engine isn't a high HP monster.   It was built to be street-able and 1 or 2 track days per year.

Thanks John, I know George P had some great info on cams especially with the open chamber.  LSA was around 110-114.
