URO Parts has reproduced Porsche 911 "Turbo-style" Lower Valve Cover 930 105 116 05, which can be used on the 1970-1972 Porsche 914-6! This valve cover has the same dimensions and material as the original 911 cover, and is available from Porsche specialists such as:

The 911 valve cover requires the ribs to be ground or milled to be installed on the 914-6 engine while in the car, see this thread: http://www.914world.com/bbs2/index.php?showtopic=264772. If you have any questions about this reproduction of Porsche Lower Valve Cover 93010511605, feel free to contact us at 800-290-5555 or "sales @ uroparts . com" (remove spaces).

Here's where the ribs need to be clearanced on the driver side (clearancing on the passenger side is similar but a bit different), photo credit to gereed75.

What's retail on these?? Also note that is not required to machine to fit a 914-6 just required to remove while in the car.

^ Thanks for the tip!

AA just added it to their web site, see the link above.
