Comp Cams 828-16 Solid Roller Lifters

Have no specific experience with those lifters, but I can tell you what they will not do: they will not 'tick' because they have bled down, nor will they pump up. A good choice.
I think the 286 cam would work quite well & have a reasonable idle, three reasons:
- being a solid, it will act like a hyd cam that is about 10* smaller
- the 110 LSA is not ideal, should be tighter, but it will improve the idle
- the shorter rod/stroke ratio of a stroker makes the engine more tolerant to duration at lower rpms.

If you already have the 286, I would use it.
