Glad they pointed that out. I wouldn't have screwed a plug in till they were bolted on the motor. I just didn't like the hack-saw look around the plug hole. I've got years and years of removing jagged edges in heads with a Dremel, only fitting I smoothed these out too... :)
I can't fix that at home, so it won't get fixed. I doubt my 360 heads now have a 5 angle valve job... LOL. Just remember, these heads are replacing stock 360 heads.
