Anyone have a comparison between these two manifolds? I have a performer rpm POWER PLUS manifold and am wondering if going to a edelbrock performer rpm manifold is worth the money. Is there a difference between the two?

What head configuration? Standard? Vortec? What engine combination?
What's the Power Plus? Is that Professional Products?

I am trying to duplicate the goodwrench quest series. I have a goodwrench motor which I stripped the heads and cam out of. I plan on using the, TFS 23 DEGREE aluminum heads with a .015 head gasket, xe 268h comp cam, 1.6 magnum roller rockers, 1 5/8 headers, 750 carb and either the professional products rpm performer polished manifold or the edelbrock rpm performer manifold.
I have the heads, rockers, gasket, headers, cam and carb(all were accumulated over the last year) so I dont need to go out and get any of that, but I have the professional products manifold that was on the engine already so I guess my point is do I go out and spend the money or do I just stay with this manifold? Trying to see if spending the money is gonna warrant it.
Also the cam that was in the motor originally didnt sound stock. I have listed the numbers below. If you could would you mind telling me if this is a comparable cam to the XE 268 H CAM? I would really appreciate it. Here is the info on the cam that was originally in it.
