cylinder head discussion

I jumped ship on the nitrous build and bought a D1SC kit. sold the nitrous kit. and will sell of the other items. I stumbled onto a ls3 engine with 15000 miles on it that is cammed with forged pistons Stock ls3 heads.. The gentleman is buying an after market block and didn't need it anymore. He was making 805 whp with this engine with the same size blower.
Now here is where i'd like some of you to chime in with your opinions. I'm still sitting on this bad *** set of heads.... should i leave the ls3 alone or would it be worth it to use the AI heads? The ls3 has arp head bolts... so i guess i'd just have to buy a set of gaskets.
If it matters car is full weight, six speed with 410 moser rear end.

You have a running, assembled engine. Dont fix it. Plus intake options on ls3 heads are more plentiful.

Thanks for the input guys. Definitely don't want to start a cathedral vs square port thread, but i guess i did lol
When you find valve wiggle on your cylinder heads after only 5,000 miles you start wondering what went wrong? I sent them to local guy to go back through them while I had the engine out due to ring issues and I'm not real sure what all he's done to them.
Why oh why did I not have Texas Speed check them for me or better yet why didn't I just save some more $$$ up and went with a set of Brodix BR7's or Mast LS7 cylinder heads from LME!
Anyway I feel the TSP PRC's are decent and I'm crossing my fingers there's nothing wrong with them when it comes to the valve guides. I'll know some more once I get the engine out of the car and the heads on my bench.
