They ship with a full valve job

I like the idea of this for a professional installer, we can setup the springs as needed, can check the margin on the valves. Some people take TFS, AFR heads etc. lap the valves anyway when new. The 2.00" intake valve is gonna give you alot of PTV to play with.

will these have the reduced valve angle so we can run bigger cams without flycutting like the 215's and the vindicator cam

The rollers are required with Bronze guides, just recomened with the Powdered metal. Stockers will work fine.

Stock rockers are good to go! Also yes they have the reduced vavle angles.

wonder what the power differences will be compared to the 215's i know a lot of people were able to hit 500RWHP with the 215's and stock bottom end with some of the larger cams, wonder if it'll be possible with the 205's and still have a little more bottom end grunt b/c of the smaller runner

Yea, it is possible w/ the correct set up. Not many stock bottom 346's make 500. There are some out there, but nowhere near the norm.

^ Yes, they will. The different valve angle changes geometry. It is always a good idea to measure pushrod length.
