Your goals are not undoable, but I hope you have planned to spend some money. As mentioned you will need aftermarket everything in the bottome end. The fastburn heads are not bad, but I would look at a big port race head like a Dart, AFR or something like that. They dont cost much more and will flow alot more air. When you are talking about making that kind of power you have to have good heads even with the turbos.
As for the turbos a pair of T3/T4 hybreds will not do **** for your goals. You need a set of large T4's and that is still pretty small for 1000HP. I would be looking into going with a large single turbo in the high 70's to low 90's on the compressor inducer. You will want a large frame turbo like a big garret from a diesel application. They will move alot of air and are very comfortable making high boost. If you are not going to do a BUNCH of research, you would be better going to a turbo shop and getting something they have put together that will work for your power goals. There are a couple that sell on ebay that have some nice turbos for decent prices from time to time. If you go to somone like turbonetics you can plan to spend close to 3k for a turbo like that, but there others putting together turbos from rebuilt oe parts that are just as good and 1/3 the cost.
You will want to fuel inject an engine like that. Blow through turbo at that level is just asking for a big boom. It will take high boost to make that power on a small cube small block and EFI is the ONLY way to control an engine like that.
You will not find a company that makes a manifold or headers for that application. You will need heavy gauge steel or stainless steel headers. Stainless is the best, but on a budget mild steel will work at low boost. But, with your power level stainless is almost a must. While velocity is important, it is relative. Typically you keep tubes smaller on a turbo engine, but at that power level 1.75" is probably what you want to plan for. For stainless it will probably cost you 2k to get someone to build them, so consider doing it yourself.
And the lower the CR the better. 7.5 is fine. Lower would be better, but it would be hard to maintain quench and get the engine to run off boost.
