im lookin for around 650 hp i just wanted to make sure there wasnt any heads to stay away from or if there was any that worked better with a turbo this is pretty much the last thing i need in my setup

Well It all depends on what your running on the engine. You could get 650hp with stock heads if you run 30 psi. The better flowing heads (as well as cam intake etc) will get you to that point with a lot less boost.

If you are running a production 5.0 or 5.8 roller block, anything much over 600hp will split the block in 1/2. 20 it awful high for a turbo when 600+ hp is easily achievable with 9psi.

Well, if he is using stock<i>ish</i> heads, 9 psi wont give him 600 hp, hell need at least 20 to get even close depending on which camshaft he is running. The main factor in running that much boost is the pistons, get some good- Not <i>ok</i>, <b>good</b> pistons. The next thing is the headgaskets, get some good head gaskets and deck and bore the block with studs. The beauty of forced induction is you dont have to have the latest in flow technology heads to get big power, its basically how much your bottom end can take and how good your tune is.
