Ductile rocker contact patch issue

See pic. The rockers are only toucing on the side of the valves. I tryed several and they all seem to only be touching the side. There's .002-.003 clearance on the side of the rocker that doesn't touch the valve. What you think? What can i do here? New rockers?
Thanks

Pic no workie

Here's another..

Are those isky rockers ? hard to tell where it's hitting the on the stem .

You could have the pads refaced, but for 2-3 thou, I'd runem as is.

They are Crane ductile rockers. In the second pic its a little easier to see that the contact sweep is right on the right edge of the valve.

another pic...

You need to add shims to get the proper positioning.
Take the rockers and shaft, insert 1 or 2 shims so to get each rocker centered over the respective valve stem. When doing this we suggest taking another head for trial fitting. And if needed a shim can be cut down by using the Dremel and sanding wheel. Add what ever shims (# and/or thickness) are needed for each rocker alignment. Also note that after layouting out the shaft, rockers and shims fit the shaft/rockers on the head and torque it down. Sometimes after torqueing down the shaft the # of required shims and/or thickness may need to be revised as the alignment can change after torque down..

Yes it takes some time to optimize but once done, the end-result will be worth it.


Just my $0.02..

i would get the pads resurfaced flat so they are contacting the whole valve stem. check ur scrub pattern after that. the way they are now will side load the valve.

This, if you look at the first couple pictures the rocker isn't offset so far that the pad misses the valve, the pad just isn't parallel to the valve stem..
