Bought from an auto parts store, same kit. I had a vacuum leak in my 2002 5.4 F150 and this is a common problem. Now most would refer him to a mechanic for that job, but I decided to do it myself. This is a moderately difficult procedure. But anyway, having disassembled everything, the new gaskets fit perfectly and are made of very good quality rubber. Fel-Pro is ideal for pads. If you need it for a rebuild or are already digging that deep into the engine, feel free to buy these. You'll be glad
