hydraulic roller lifters issues

Yes it is a 340. I was thinking that I might save myself a lot of problems and expense and use the flat tappet cam. Would it be worth it to use roller rockers? I am planning on using edlebrock 7576 intake http://www.edelbrock.com/automotive/mc/manifolds/chrysler/rpm-air-gap-sb.shtml and 60179 heads http://www.edelbrock.com/automotive/mc/cylinder-heads/chrysler/performer-rpm-sb.shtml
