cracked ex manifold or gasket
I have read that the 454 chevy cast iron exhaust manifolds are prone to cracking. Is it easy to see? I would rather that the gaskets are bad

Instead of worrying about marketing hype, search the internet for real dyno comparisons. Or you can search for a rolled Nascar car photo, where you can see the stepped exhaust. Understanding the whole concept of keeping the air moving, the concept makes sense.
BTW: When, not if :) the bolts break off that hold the donut, most auto parts stores carry the equivalent of a miniature C-clamps to bolt it back together, so you don't have to drill out the old bolt.
