OK need help, Friend Wont Listen too me, I maybe Wrong

if i recall correctly, you shim the rocker arms.

found it. http://www.cranecams.com/pdf/453e.pdf?PHPSESSID=293f0be1774a4434f997d24451c4e94b

it's a pdf file so you'll need acrobat reader.

the 1.6rr if they are stud mount then they are adjustable, pedestal mount are not adjustable. If he has those 1.6rr, tightened all the way down on the stock head pedestals then it is wrong, you have to get the conversion kit to make stud mount work correctly on a pedestal mount head. If he has the rockers tightened down all the way to the pedestal on the head, then you should be getting far too much lift therefore, when the spring bottoms out and the pushrod is still coming up, bending the pushrod.


I think that would be a good guestimate of what is happening

Stock heads and mount rockers - something is wrong, unless I misunderstood.
