[DeTomaso] Rocker arm alignment

[Ken Green]

I'm very much an amateur at this, so take this with a grain of salt.
 
I had the same problem and I still worry if I got them aligned well enough.  You can bend the pushrod guides, and even cut and weld them.  I think the holes in the guides are a little over sized, so sometimes you can loosen the rocker arm studs and move the guide a bit, then tighten.  Probably fill the gaps with locktight.  I even used some different guides (Manley and comp Cams) on different cylinders and one brand matched better that the other on the different cylinders.  I'm surprised the engine builder was satisfied with what he gave you.

Subject: [DeTomaso] Rocker arm alignment


Just got my engine back from the builder.  After I got over the bling factor I noticed some of the rockers are not lined up directly over the top of the valve stem tip.  
See picture links.  These CompCam rockers are installed on CHI 3v heads.  I've rotated the engine several times and the alignment doesn't differ.  
All of roller tips are hitting the center of the valve stem so I think the pushrod lengths are good.  
It's just the offset side to side on a couple of the rockers that has me worried.  
Appreciate any opinions.
