Comp Cams 828-16 Solid Roller Lifters

I'm sure this may have been covered before, however l'd like to hear from people with direct experience. I'm building a 340/416 with mildly ported iron J heads, 9.5:1 static comp, Weiand Stealth intake, Carter Comp Series 750 carb, Doug's 1-5/8 long tube headers. The car's a 67 Barracuda with 4 speed and 3.23 sure-grip 8 3/4 rear.

Not racing this car, just want a strong street / reliable motor that sounds cool, pulls hard and turns the wheels at will. I have a new set of Comp 828-16 solid roller lifters and a Comp XR286R cam. The cam is a little too much for what l want, so l was thinking of getting another stick, such as a Comp XR268R, which is 230 / 236 @ 0.050" 0.552 / 0.564 lift LSA 110.

My question is, do these Comp lifters run reliably on the street, l do realise there is some clearance to be done in the lifter valley for these to drop in? Also what do you guys think of either of the Comp solid roller cams l've outlined, in particular the smaller of the two?
