Looking for some input on 360 LA build

Posting the actual cam specs is SUPER HELPFUL!
Posting part numbers is OK at best. Saying or describing what it actually is, is better. Example; your comp timing chain. You have one! Terrific! There are so many options to which one it is and I myself (and few others) will not look it up to know exactly what it is. No one wants to do the homework on answers you should have provided.

As far as what head to use, it would be the best one you can afford. Hands down! Maxx 171 SB Mopar (Sold in Pairs) - PROMAXX Performance Products
Though I say to make the stretch and get ether;
Shocker 185 Mopar CNC (Sold in Pairs) - PROMAXX Performance Products
Or the Trick Flow heads.
Definitely looking at those promaxx heads they seem to be the best bang for the buck on the Mopar market
