/6 Valvecover

@ boosted - I just tried again myself moments ago and it says your inbox is full. You'll need to delete some stuff to make room and try again.
@chignikred - Boosted was kind enough to post a photo and it shows the main visual difference between the two types. On your valve cover the bolt holes all line up on either side of the cover. On the hydraulic type the right side (as installed) are not in a straight line.
