Engine Replacement. Help w/ Manifolds

[The Slider]

Im replacing my 2.9l in my 86 B2. Should I leave them Exhaust manifolds on the exhaust or should I leave them on the engine. I just thinking which would be the easiest to do when dropping in the new engine.

Thanks!
Chaz.

You always want to leave them on the engine. Taking exhaust manifolds out on the vehicle is one of the biggest PITAs ever.

Cool! Thats all I needed to hear. Ive done all this once before but it was YEARS ago and my brain cant remeber that far back.
