your question is too general/generic. there are too many head/cam options to give you any kind of an answer. if you're simply asking if they've got a good product, then the overwhelming answer would be Yes, they do. hp/tq figures will depend on how wild you want to go and what you've got for funds. figure those 2 out, factor in emissions, then give them a call to discuss your options. there are several quality vendors here that you can research, just take your time and....."Search" for topics related to x heads or x cam. hope that helps a little more than the "dicks" answer.

Yes they are good. They have great customer service and are great to talk to. As far as numbers. It all depends. I gained 109rwhp from my MS4/PRC Heads combo. That is with a SAFE tune. No intake or TB work and no pullies. Some people gain more with less of a cam. It all varies with what your car is doing now. What you have done for supporting mods and things like that. My buddy kicked out 343 with a Lid and Exhaust. I on the other hand was not so lucky. I got 339 with Lid, Long tubes, ORY and exhaust. Just research, research, research. What are you long term goals, what are your streetability goals. Do you want power higher in the RPM range or lower. Just talking to one of the guys at TSP will help you out. Good Luck
TSP makes great, proven, head/cam packages for the price, the only problem I see with them is that they throw in 7.4" pushrods with their packages when in most cases a different size should be used.
