Are roller valve trains noisy?

I noticed an increase in noise when I went roller rocker, and I know my rockers are adjusted fine.

It depends on quality of your valvetrain components, better roller rockers will make less noise and vice versa.

my roller motor is quieter and alot smoother than my previous flat tappet

Man, thats what I'm saying too. My current roller 302 was built to go in my previous '89 GT. It has Crane pedestal rockers(same as '93 Cobra factory rockers) and a lumpy Crane roller cam. The whole thing makes zero valvetrain noise.:shrug:
