Turbo valve cover modification for installation in a 6, Anybody done it? Options

[bdstone914]

I have a customer who wants to add billet lower valve covers to a 6 conversion. He had one machine shop botch the first pair. Anybody done this and know how much material needs to be removed to clear the suspension point? I drawing showing the area to machined and the finished thickness would be ideal.

Please pm me if you can help

No need to shave the whole valve cover. The extended fins are there for cooling. Based on my little knowledge, all one has to do is to reduce #5&6 cylinder side .

I doubt if it would make much of a difference.
My VW bus type one engine has a 3-1/2 quart Gene Berg oil sump, it's a huge chunk of aluminum covered with fins. Berg did all kinds of testing and only got an average 7 degree temp drop. The benefit was the added oil capacity to keep up with the high volume oil pump.
A couple fins on a cover isn't going to amount to a hill of beans.

As far as being weaker the Capt'n used to always laugh at people who spent money on turbo covers, as he felt the aluminum SC cover was more than strong enough...and dirt cheap.

Mark, where would one go to buy these dirt cheap SC valve covers, and how cheap is dirt cheap?

EDIT: To refine my question, what it the best parts yard that has fair pricing and shipping charges?
