[DeTomaso] Rocker arm alignment

[Garth Rodericks]

Hey Sean,

I found the same thing when I assembled the valve train on my new 383 stroked Cleveland with worked Edelbrock heads.

I adjusted my Manley (42163-8) pushrod guide plates.

I used a flat punch and a small hammer to tap the fingers of the guide plate to center the rocker's roller tip over the valve stem, taking care that the pushrod had the same degree of drag/freedom within the adjusted gap as before. I shifted the rocker left and right to make sure the roller was centered on the valve stem.

I'm no expert, but this seemed like the right approach to me. Hopefully the experts on this forum will confirm my actions.

Cheers!
Garth

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. http://poca.com/index.php/gallery/?g2_itemId=38019 http://poca.com/index.php/gallery/?g2_itemId=38017
