Help with cam selection

Here are a few answers to the questions, No I have not had any flow tests done. The intake manifold is an older edelbrock tunnel ram. For exhaust I am looking at a set of TTI headers. I would consider something else if there are any other suggestions.

I will give Dwayne Porter a call this week and see what his thoughts might be. Does he just do heads or do they get involved in camshaft grinding?

The Mopar camshaft is a flat tappet and I want to use a roller cam. I checked the summit listings and didnt find any mopar roller cams. Do they make them?

I dont have to make a decision right now as I am just starting on the car and it is going to be a 2 year or more project.
Thanks for the suggestions and interest so far.
