Bolting on a pair of FE pentroof valve covers will greatly enhance the appearance of the engine compartment of your small block equipped Cobra replica. These plates are intended to adapt Ford FE valve covers to any standard Ford 289/302/351W cylinder heads that could normally use a standard small block valve cover including GT40, GT40P, GT40X, Edelbrock and Holley. My adapters are produced from quality Alcoa 6061 aluminum plate, CNC machined to close tolerances and have been designed to work primarily with cast aluminum FE valve covers from Ford Motorsports and other quality suppliers. Roller rockers on standard cylinder heads should clear nicely. These adapters may also be used with the chromed stamped steel pentroof valve covers available from T. Branda and others but in certain cases the bolt holes in those covers may need to be slightly elongated with a round file to fit the mounting studs. This is the result of a manufacturing problem with the repro covers and not with the adapters. If you plan to use stamped steel valve covers with this adapter kit please review Special Instructions For Steel Valve Covers. Heads with non-standard valve geometry and/or stud girdles have not been tested so I cannot comment on those applications. Stud girdles should not present a problem with the adapter plates themselves but the added height of the girdle might cause interference with your valve covers depending on which FE cover you plan to use. My express warranty certifies that these adapters are free from defects in materials and/or workmanship and will perform as stated for the applications specified. No other warranty, express or implied, exists. If the purchaser chooses to use these adapters for any application other than those specifically stated it is done at the purchaser's own risk and voids the warranty. Any modification to the adapter plates voids the warranty.
I can usually ship within 24 hours of receipt of payment. The adapters come with all screws and washers needed to mount the adapters and valve covers plus a pair of premium steel reinforced rubber smallblock valve cover gaskets. The kits cost $149 plus actual shipping via Priority Mail. Please provide your postal zip code to calculate shipping charges. I accept PayPal OR a money order made payable to me at the address I send you with your quote.

THE KIT INCLUDES:
1 pair 3/8" thick aluminum CNC machined adapter plates
1 pair smallblock Ford valve cover gaskets, steel reinforced rubber
Cork gaskets are NOT recommended. They harden, crush or distort, and stick over time.
12 1/4x20-1.00" flat head Phillips screws, 10 standard, 2 with small diameter heads to mount adapter plates to the cylinder head.
10 1/4x20-1.25" flat head Phillips screws, 8 standard, 2 with small diameter heads to use as FE valve cover studs
10 1/4" 18-8 stainless steel washers
10 1/4" 18-8 stainless steel lock washers
10 1/4x20 18-8 stainless hex nuts
MATERIALS AND TOOLS NEEDED:
#3 Phillips head screwdriver, 7/16" socket or nut driver
1 tube of Permatex Ultra Black (Part #598B) hi-temp silicone RTV. Other RTVs do not posess the oil resistance required for this installation.
1 small tube Anti-Seize Compound (Optional)
1 pair Ford FE valve cover gaskets, FelPro #VS-13049R (preferred) or Victor #VS38308R
10 Valve Cover Bolts, 1/4x20, Ford Motorsports part # M 6680A recommended

The adapters bolt onto the smallblock head with 1/4x20 flathead screws. Instead of 5/16" bolts to attach the FE covers, I opted for 1/4" studs. This allowed a little more room to jockey the FE cover into place and allowed me to use the Ford Motorsports short retainer nuts which I think look great. I highly recommend the use of short valve cover nuts such as Ford Motorsports Part #M 6680A.
A good source for reasonably priced genuine Ford short nuts is:

The adapters follow the shape of the polished 427 LeMans valve cover in order to hide them from view when looking at the motor. I chose a pair of polished pentroof covers from Ford Motorsports. On the right cover (passenger side) I installed the PCV grommet because the PCV port on my carb faced in that direction. On the left cover (driver's side) I decided to use a nifty twist-in oil filler tube (part #EG-381) from Virginia Classic Mustang. I thought this tube would make it easier to add oil without dripping all over. This tube uses a Ford Motorsports push-on breather also from Virginia Classic Mustang (EG-382) similar to the smallblock oil filler setup. This setup costs a few bucks but I thought it would work better than having tto aim oil at the grommet hole. One thing to note is that when I finally installed the dual quad intake setup shown below I swapped the grommets side to side to place the PCV valve on the driver's side of the motor. This is because the PCV tube in the base of the dual carbs ended up facing the driver's side of the motor because they were running backwards. See the photos below.
I have Crane roller rockers on my Edelbrock aluminum heads and have absolutely no clearance problems. The adapter plates are made from 3/8" thick aluminum plate which actually provides 1/2" additional clearance over that of the cover itself (3/8" plate plus 1/8" for the second set of gaskets). Scroll down to see the photos of the plates as installed on a demo head as well as the finished installation.
