Depends on your goals. Generally speaking, if you want more top end, go with longer duration cams. If you want better low rpm performance, you want a shorter duration cams.
I am partial to the JWT cams because they provide more lift for a given duration than any other cams I have seen for our cars. The upside to more lift is that, in general, you get more air/fuel mixture into the cylinders. The downside is that you can't run those cams past about 7300-7500 rpm.
If you want to run past about 7500 rpm, you will want a cam with lower lift. In that case, take a look at the GTM and Brian Crower cams. Also, you should have a billit girdle to add rigidity to the block.

Personally I like the lopey sound...thats what I would go for.

Terry is right, A good cam is the JWT S1 they are not super aggressive I am running JWT C2 I had JWT S1 and by changing to the C2 it moved my power band up up about 500rpm. I went from putting down 525ft/lbs @ 4500rpm to putting 525ft/bs at 5000rpm after swapping out cams. If you look on Jimwolftechnology.com I think it has good descriptions of his cams. I would advise you to get the JWT valve springs if you get the cams, they are not overly expensive.

JWT states that you must use their valve springs for their "C" series cams.
Their "S" series cams are designed to be compatable with stock valve springs, though you would probably want to use the JWT valve springs if you want to push much plast 6500 rpm.
