I had both a set of FRPP headers and BBK shorty headers.. Actually the workmanship on the BBKs was better -- a lot less welding slag in the port-to-flange mating area. Plus where the primary tubes were mated better to the collector. Also, the flanges on the BBKs were thicker...
The only advantage the FRPP headers had over the BBKs were that they were made of stainless steel. They should last a lot longer.
It could have just been a bad set of FRPP headers -- I don't know. But based on my experience I would chose the BBK over the FRPP. But I ended up returning both of them and went with a set of MAC longtube headers. And believe it not -- the MACs were put together better at the collectors and flanges than either header.

Went in the first time fine, but the next time I needed a breaker bar and a friend to pull on it to line up the header bolt holes while I tried to put the bolts in. grrrrrrrr...... The heating and cooling caused them to distort.
), he has one price for FRPP shorties and all others with one piece flange and like double that for any garbage that MAC makes, since they "don't fit, new, or old, or even and they are garbage" They do make good copper header gaskets, 1 year no leaks
