LA small block,Do you put an oil passage in your head stud?

You can buy rockers that take oil from up through the pushrod and oil the rocker shaft with that pushrod supplied oil. When you use that system, you block off the oil that comes past that stud anyway.
If I were spinning it to 9000, that's the system I'd be using in the first place.

We did have oil through push rods and gulled every one. Push rod angle on and LA is terrible. We are going to offset lifters to help fix that. All the GMs he builds have oil through . We were spinning it to 7800 -8000 every shift . I said it has seen 9300 on the recall . Never with Steve driving only when I played with it.
