SBC 327 Head Choosing Help?

[Rude Dude]

Hey Guys

I need your suggestions I am like everyone here mostly on a budget on. A good friend gave me a complete rebuilt 1968 327 Large journal SBC bored 30 over. It came with power pack heads that need work plus I dont know if they are set up for unleaded fuel. I want to stay with stock reground cam since it has hardly any miles and I dont want to remove it. I wont be doing any racing just cruzin. do you have any suggestions as to what set of new or used heads will work good for a stocker 327 motor for unleaded gas. I dont want to put later vortec heads cause I already have a 12 bolt polished intake and straight across valve covers unlike the vortec design. And I would like to use accessory brackets that bolt to the heads. I have looked on egay and craigslist but all the new selections have 202 valves. I also have a set of 305 High Output 14014416 heads (184). These are off a camaro Z28. Any suggestions as to what I should run or look for and would the 305 be okay for this application? I know this is alot but info but any help would be appreciated.
