Building a 350...what heads to use?

Right now i have a 6 cylinder camaro (shown below). In the next few weeks, I will start building a performance 350 to put into it. I noticed that Edelbrock (on their website) lists all of their cylinder heads and intake manifolds as being compatible with certain year engines. For example, they list the Performer RPM heads only for engines made up to 1986. there are other heads for '87 and later engines. Does this mean that if I were to pull a 350 block out of a 92 Camaro I would have to use the other heads and not the Performer RPM? Or are they interchangable? Are all heads for the fuel injection era, '87-present, centerbolt heads? This may seem like a dumb question, but I'm curious and I don't want to spend money on things I can't use.

Also here is my planned setup.. tell me what you think.
- Edelbrock performer intake manifold #2101, 600cfm carb #1405, perf. plus camshaft #2102. possibly edelbrock performer heads #60909 but not sure. with this setup I should be around 330hp, but its my understanding that if I use different heads I could be around 400hp+. Haven't completed my research yet. What heads do you techs recommend? Or what would you recommend to get me to around 400hp without a blower?

I plan on using a used factory 350 block, probably not bored, stiffer pushrods, and ARP connecting rod bolts. also rebuild 700R4 to handle V8 power with parts from www.transmissionhead.com
