Hemi head identification

"Narrow intake ports with an injector notch are early 5.7 heads. Square intake ports are late 5.7 (Eagle) heads. Square ports with open chambers are 6.1 heads. Square ports with narrow/closed chambers are 5.7 Eagle heads. 5.7 bore 3.92". 6.1 bore ~4.055~".

Found that on Moparts with a quick search.

I'm not seeing those numbers identified. But I'm thinking you are looking at an '03-'08 5.7

Post a pic of the intake port opening and we will be more able to identify it for you.
