stock or cam comp are strong
are you full ferrea valvetrain (seat retainer spring)?
it should be fine. the part i believe can fail it the roller.
here a picturees of a roller.
roller from saturn 05 are cast iron. the other year or ''pressed'' instead to be cast iron.
that can be a fail for you
a roller make the link between cam lobe and the spring.
it works as a lever.
roller cast iron is light gray.
roller pressed is more beige.
have titanium seat and retainer give less weight to move = hp gain and no lost in TQ.
a lighter rotation part like a pulley or a flywheel = +hp but -tq.
