Best flowing cylinder head options for an 07 5.7 hemi

I have a 2007 Chrysler 300C with the 5.7L (345ci) hemi! I wanted to see what options I had as far as getting better performing cylinder heads. I plan on tuning and putting a large cam in. I want to be able to benefit from the higher lift and duration. I do also plan on running a small shot of nitrous later on I’m the future. I know you can have your current ones sent away to be ported and polished, but I’m not sure how long that takes and would need them back in a decent time.
