Like Pat says ...........

If it's a Mark IV block the heads should work. Gen V they will likely leak coolant into the valley ..............

thanks alot guys i really appreciate the help ..i'll just sell the heads, the last thing i want is more car headaches..
the carbed lt1 was a conversion that i bought used from a guy. if you run a search on camaroz28.com you will find lots of info...however i tune fuel injection systems and if you set up the f.i. right it is much more street powerful than the carb..(can't beat f.i. low end power thanks to always ajusting air fuel ratio and timing) if your going for max power than its a toss up...thanks again guys
