273 ADUSTABLE ROCKERS Q #2

Man I hope these things aren't big block. Is there any market for big block rockers if they are?

2 holes.......One round one adjacent to the rocker arm to supply oil to the ball and socket, and one hole in the middle of the banana groove at about 5:30 when viewed from the end.
These are Isky's on a 440. Copies of oem but the adjusters are different and have a locknut. Looks like they are offset. The small block ones aren't.
