While grooving the #4 cam bearing is fine Indy heads are not fed oil that way to the rockers. They are fed through oil lines at the back of the heads. Burnt tips are obviously from an oil issue. Look for issues with the rockers that had pushrod problems. I do not and will not run the Indy/Dove rockers but you may want to check them for obstructions or possibly the adjuster is out to far not letting oil pass through to the tip....If that is the case the pushrods are the incorrect length.
