Local speed shop (even ebay has them) can get you the -4's, thats what I used also. Dan, those 6's that you used are huge man,lol. I like the fact that you mounted it up right. How do people not understand, having a oil cooler mounted with the hose's at the bottom makes no sense. Might as well have a 1 row cooler then,lol.
P.S. Don't forget to remove that tape from your tappet cover Dan.
