Comp Cams 828-16 Solid Roller Lifters

Thanks to all for your replies to my initial post. Seems to be a divisive topic, some have used these solid roller lifters in street driven cars with good results, others warn of catastrophic failure. Hmmmm, I have a new Comp XE274H hyd stick in the stash that I could use. I'd like to make 420hp & 480tq in a very streetable combo with mildly ported J heads (2.02/1.60) 416 cubes, 4 speed and 3.23 gears.

Anyone have any experience with this stick in a similar build?

Any other flat tappet camshaft recommendations, solid or hydraulic?
