Sealed power will be fine for your build , I have used them many times in the past , never a issue . The quality control issues at comp cams is REAL ! I dont know whats going on over there but they are about to go into the abyss of the hot rod world if not gone already ! It has been rumored they started useing china blanks and other [ global components ] ! I really hated to hear that , i have used there products on many builds in the past . I know two guys that have had to pull cams in the last 6 months , one with lobe failure and valve spring issue and one with oiler issue on AMC engine. And a lot chatter about there customer service no longer being good .
