I'll need to raise my rocker stands .100" to get the geometry where I want it. I was already a thread short on the oil feed stud when snugged and am now too far beyond that to be comfortable. I have C4AE-G heads and using the corresponding studs from Precision Oil Pumps. I emailed them to see if the set they sell for Edelbrocks / HR heads are longer and have not heard back. Does anyone know if they are or if there is a different stud kit I need to move to now?
