My track has no cu Inch rules just cast in cast out and no strokers, and no after market heads or vortech. I have decent 406 but it has dart heads. Any recommendations for factory head to replace the darts?

Those are dumb rules. Stupid track promoters want racers to use 20-30 plus year old heads. blah blah blah.
To answer your question, I think it's 882s and 487x are the ones you want.

With those rules and no stated compression limit, camel humps would probably be your best bet. I know a guy that has a bunch of sets of them. If you need a set for cores let me know.

I would go with camel humps or 041 heads. Our rules allow any OEM heads, and a lot of us have been using the GM performance products heads (bowtie heads), but I doubt your rules would allow them - but it wouldn't hurt to ask.

Just watch for the steam holes even on alki. do matter on matching clynder temps in the middle of the engine where its most cridical!
