Valve cover choices
I need to replace both my upper and lower covers. A hour of surfing the net (many it was two), and I still don't know what I should buy. I'm not going to fork over $300 to get the CNC ones, but what is the smartest choice?

You'll spend more than $300 for the billet machined which are the best. Roughly $300 for the top pair and $300 for the bottom pair so closer to $600 total. Add gaskets and shipping and you're getting up there... gaskets are then reusable and they won't leak. I really like the Hargett pieces the host sells and use those on my engine after having a local business add milspec black hard anodizing. Smart money in my book for no leaks and a much better, modern gasket design.

     I had Hargett send the bottoms without ribbing on the outside so I could add heatsinks.

Couple more
   Headers are wrapped.     You may have gathered that I'm one of the few who believes the functional area of the valve covers is an area of the engine that is neglected and vastly under-engineered relative to the rest of the engine design. Playing with sandwich gaskets bonding to surfaces, dripping, warping and cracking covers wasn't a game I wanted to play. YMMV.

Yep, nice bling but none of that will work in a 914, just get turbo covers and mill down the ribs.
The tops are standard issue and you should be able to find a good set in the FS/WTB forum.

I bought a new set of lowers from Patrick and they are milling them down for a reasonable cost. Still looking for the uppers. What's the real difference between mag and aluminum?
