Thinking outside the box
It you want to compare late model chevy heads to mopar heads you should probably compare them to the new 5.7 and 6.1 Hemi heads.
Indy makes some serious heads for small block mopars that have big ports and can be ported to flow some good numbers. Indy also sells IndyBrocks which are Edelbrock heads machined like a TA head so no push rod pinch. Good heads are available now you just have to have the deep pockets to put a combination like that together.
