I have a 70 cuda 440,i am wanting to swap cylinder heads,i have 2 inch primary tube, hooker headers on engine, there doesn't seem to be much wiggle room between headers and inner fenders to move them out of the way to access the head bolts for removal.has anyone done this,or do I need to drop the engine & k- frame out the bottom of car for easier access.i don't want to scratch plum crazy paint on inner fenders moving headers around. thanks jim
