Original solid cam vs. full solid roller

[luzl78]

What would be the best setup to use in my 67 l78? I have a couple nos "143" solid cams and all nos drivetrain for it or should I use a new aftermarket setup with a full roller setup. Car has m21 with 4:11 rear and I'll be using m/t scavenger headers with chambered exhaust. I understand the exhaust restriction but you can't beat the sound. I'm using my original valve covers. Is it just a matter of less friction with the roller setup and more cost? Thanks. Jeff
