Flat tappet to solid roller...

I talked to Hughes today about the cam I should get.
They suggested flat tappet cam with 1.6:1 rockers that I have and said that unsually cam manufacturers dont take advantage of Mopar lifter size that is bigger and buying solid roller will do nothing but drain my wallet with minimal if any effect on power...
They said that if I want to spend more money they can get me roller, but they dont recommend it.

Suggested cams were:
1.
Hughes Engines
2.
Hughes Engines

Also EDM type of lifters were suggested to extend life of both cam and lifters.

Now I am a bit confused...
