Actually if you look at the Butler website there apparently is a condition where a BBC style rocker is required. They have a set of roller rockers that are only for Edelbrock heads that have an offset built into them for when heads are slotted for 1.65 rockers. They are 989 dollars though. I talked to my machinist because I was worried this was what he was talking about and I was gonna have to spend another grand but he said it was just the voodoo rockers.
