Spark plugs for one, lol, I have owned one big block powered Mopar and all my other stuff is small block and FML is changing plugs in a big block with headers a nightmare!!!!!!
The only plug I find a little tuff to change is # 6, a long wrench from the underside solves that problem or drill an access hole.
I can change plugs on a low deck big block in 15 - 20 mins, with headers or manifolds.
