Heads and Cam for this Spring, GT40X?

Ok, well as soon as my tax return gets here i'm doing the HCI. I allready have a GT40 upper and lower intake ready to be installed. I'm going to have the shop install heads and a cam while she in there since it will save rme labor in the long run. The shop recommended a set of GT40X heads and a E cam. Is this a decent combo or should i go with a TW or AFR and a more agressive cam? How about aftermarket rockers, I see people throwing them on too? I'd liek to get everything together so i can just bring it to them and have it all installed at once. Any opinion on a powerful but cost effective setup?

Thanks

will throwing on 1.7 rockers make a difference in power? Is that cam loopy?
