Notice the smooth clean look on the drivers side of the cover. All other covers are full of ripples to go around head bolt holes. This cover also offers more internal clearance than competitors units. 12Bolt roller rockers fit with no issues.
It is offered as a unpolished, shot blasted or polished unit.
You will also notice the lack of a oil fill hole. There are 2 options here.
1. Machine a oil fill and PCV (25.00 each hole)
2. Add a bolt on the side oil fill and PCV (preffered). Also called a breather adaptor. This is the cleanest look to find on your inline 6. Still allows use of PCV .
