We recently were tasked with replacing the headers on a 430 Scuderia. Our friend Greg purchased a set of Capristo Headers during our Black Friday Sale and had us install them. The installation would have gone smooth but one of the studs snapped and half the stud was stuck in the head. We ended up having to drill out the stud and use some reverse out bits. We ran into some other issues that ended up making the job take significantly longer than expected. I suppose this is pretty typical.
