    PCE281.2003 is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Could be better In installing these I find a couple if issues. Foremost is that I cannot use factory bolts. My sockets won't fit between the "cups" under the springs in a couple spots. Second, the oil return is neither large enough, tapered at the top, nor does it line up with the block. I'll have to chamfer the block so the oil won't be obstructed getting out of the head. I shouldn't have to deal with any of these issues. Keepers: According to Lunati ( the cam I chose ) I must remove the inner springs during the break-in period. The keepers are a pain, so I hope they hold well. I haven't fired it up yet, but I'm hopeful for what improvements they bring.
