Exhaust Manifold Recommendations - 1972 GMC K1500

[Portland68]

Looking for recommendations for exhaust manifolds for my 72, dad and I pulled the motor for a rebuild and one of the stock ones had a major crack so I'm looking to upgrade a little bit.

I've been looking at the ram horn style center dumps but was curious what members thought and if my options were limited because the truck is a 4x4.

Thanks!

edit: Looks like my picture uploaded sideways again but there she is last year after a fresh brush on clear coat - good from 20 feet!
