Trick Flow heads
I would look at just getting your stock castings ported.
Those TFS heads for the LT1 are nice out of the box VS stock unported heads, but even higher levels of porting those heads dont show to be worth the money.

Where did you get that from? I thought Lloyd and AI were making sweet numbers with those heads ported. I'm to lazy to dig up the post though. Anyways for the most part I agree. Get your stockers done up for the money and youll find the extra power you seek and more and if you dont have a cam for your setup that would be the icing on the cake. What are your reviews for the LT1 STS setup? I kinda want one for my 12.1 C/R setup 
You are probably looking to drop compression some so you can raise boost right???
If so might I suggest you buy Trickflows from AI Summit has them as cast assembled for $1360, AI has a couple different porting levels but they start at $2195 and that includes the bare casting that they work and assemble.

However, I down have a blown application so I don't know how this would affect your performance, but I know for my N/A setup i am definitely glad I went with the TFS castings

I agree with 96 capricemgr With the 64cc combustion chamber they are much better suited for a boosted car. Lower compression. AI can work a sweet set of TF heads for your application.
