You need more oil to the top of the engine. Start by replacing the 3/8 oil pick up with 1/2 inch, and high volume pump. Do you use lifter bore bushings? Also, run additional oil lines to each oil galley by tapping into them and oil supply line tapped into the block near the oil pressure sender. Problem solved.

Groove the #4 Cam Journal like a HEMI.

See you at the races,

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.
