erson rocker and arp stud kit question
i have the arp stud kit for my erson rockers for my 445 fe, i was wondering if all the studs are undercut to feed oil to the rockers?, the studs are at the machine shop so i was just thinking ahead from what i remember i thought they were all the same size?.

look at them......are they undercut? if no they need to be

Studs are not undercut, but do not need to be - don't worry about that. You need to use the AN washers in the Erson kit - NOT the thick washers from the stud kit. You'll likely want to restrict the oiling anyhow.

Barry, why is that? I used the thick washers and have seen no oiling problems that I'm aware of..
Thanks

No oiling problems. But some of them will interfere with the rocker bodies...not always..but sometimes.
|
does oil still get up there without the undercut? are the clearance holes larger than the ford?

Oiling Studs
The oil does not go thru the stud on a FE it goes around the stud in 2 places. If you look at your head you will see a counter sunk hole on each head, in that countersunk hole you will see a hole on the side of the counter sink, this where the oil goes up thru your stand an thru the tube an oils your rocker arms.

i have seen pictures of the under cut bolts so i was unsure about the studs they are all the same so i wanted to make sure, i think erson said to use washers no larger then .750 the ones they supply in the box look thin . i think the arp washers are not completly round so they hit one way and the other way they are fine. i have precision oil pumps screw in .090 restrictors instslled in the edelbrock heads.

i'm used to seeing the factory studs with a reduced diameter bolt, the clearance holes in the ford stands are a tight fit so they are clearanced for the oil travel up the bolt( yes the outside)
i was wondering if the erson stands have a larger clearance hole for the bolts or studs in this case, making the undercut of the stud unnecessary.
