[DeTomaso] roller rocker arm alignment, lose the Manley pushrod Guides !!!

[wkooiman at earthlink.net]

The only issue I had with CompCams guide plates is the pushrod rubbed at the base of the U.

I've mentioned this before.  The pushrods are supposed to rub on the sides, not the base.  If it rubs on the base, it eventually breaks the guide plate.  It's an easy fix with a dremel.

They were perfectly aligned otherwise, though.  I didn't have to resort to cutting and rewelding.

>I've been struggling trying to get a satisfactory alignment of the roller with the top of the valve stem.  I have Manley pushrod guides and one of the real pains is that a step on the intake valve side is so close the hex on the rocker arm stud that I can't get a deep socket on it, and end up triple nutting it to get the 65 ft-lbs the studs are spec'd for.

I can't order one Manley, but can order one Comp Cams guide, so I order the CC guide.  First, I notice that the Comp Cams guide has a slightly different step, and I can get a deep socket on both studs, BIG IMPROVEMENT.  Then I torque the studs and set the rockers on to see how far off they are, and they are dead on.
