For those with EDCs, front tubbed, etc...

I was wondering how hard it was to do engine work with tubs, edcs, relocated tanks, etc...Dylan and I talked about it for a second when we detailed my truck and were thinking that those of you with cluttered engine bays must have a hard fucking time when something goes wrong. Have you done all of your engine modifications BEFORE your laid it out or have you done mods after? Is it that hard to change plugs, wires, install headers, fix leaks? Just trying to get a feel if I ever get around to baggin my truck.

Thanks.
