Valve Cover Gasket Part Number?

About three weeks ago I replaced my leaking valve cover gasket. It had the cork style installed and the kit I purchased had the blue rubber gasket with the upper and lower intake gaskets Felpro VS50043 R-1. Initially it seemed to be doing the trick, and then a new leak developed around the cam block seal. I thoroughly cleaned and stoned the mating surfaces of the head and valve cover, and properly torqued the fasteners prior to installation. So I pulled it apart yesterday and noticed that the rubber gasket had two ribs on the top of the cam block sealing area, as if it there were grooves in the mating surface of the valve cover, but their are no grooves. So I pulled it out and installed the cork version Felpro VS50126. This one had two holes on the vertical cam block seating area, as if being set on dowels. Both packages listed the Ford Truck Model Years but nothing about the TC. I am quite sure these are getting incorrectly cross referenced by everyone as the corect gasket. I did intall the cork gasket and so far so good. Anybody else run across this?

I've been using the blue Felpro for years w/ no problem. Even had the cover off and on several times. I think the groves you mentioned are to keep the gasket centered under the VC.

These are PNs from 2002:
Felpro Part# 50043 R-1, comes in a set with part# VS 50043 R-1

Most people prefer the Ford rubber gasket even though it is more expensive.

Make sure the valve cover isn't warped. It has happened.

i had been using the blue felpro for years, but i had issues recently with it. the metal dowels were getting stuck on the valve cover and making indentations. so i had a big leak. i ordered ford one and even tho its twice the price the quality is superb. no dowels its basically a metal gasket covered in silicone to seal. been on a year without an issue.

^^^^ +1 Part # is F57Z-6584-A. I have had that gasket on mine for 11 years and zero leaks. Not even a seep..... 100% dry. The Ford gasket can be removed and replaced several times and still be as good as new. Actually cheaper in the long run.

The Ford ones are so durable I usually get them from the JY when I am getting the roller cams and followers.
