Help on 408 build

I’ve run so options with an engine shop a couple days ago and I think I’ve decided to go the heads and cam route since I wanted to go with aluminum heads in the future anyways. Not sure on cam yet maybe you guys can help me out a little bit more than you already have. Here are the heads I plan of going with (Promaxx shocker 185 CNC)
Shocker 185 Mopar CNC (Sold in Pairs) - PROMAXX Performance Products

What do you guys think of these heads?
