Clutch Linkage

I put in a McLeod clutch on my Dart. I haven't run it yet. Car is still being built.

Been reading a lot about beefing up the z-bar and the firewall because of the stronger than stock pressure plate. Question I have, what needs to be done? Does anyone have any pics of what modifications are needed? I'd like to address these before I put the linkage in. I'll be putting a set of TTI headers on this car as well, and I don't want to make any modifications to the z-bar that will interfere with it.

Appreciate any advice anyone can give. I like to do it right the first time, and anything anyone can recommend is very welcome.
