Everything you touched in removal,that you can get to, touch it again and make sure its tight, hooked up, connected etc. Bleed air from cooling system, oil full, all other fluids full, exhaust tight, intake hooked up and tight, plugs and wires good and routed well, fuel lines hooked up, etc. Pretty much a good visual should help you locate any possible issues before they become anything bigger.

A lot of noise and the possibility of blown exhaust manifold gaskets, if it's the exhaust manifold/header flanges you are referencing. If it is indeed the exhaust manifold/header flanges, what bolts are you using? Are you using headers?

First find a way to attach all 3 flange bolts securely on both sides
