1.65 adjustable rocker arms

Aussie company who make some really good gear, the 'platinum series' are very high quality but $1200US + shipping is a bit up there.

They make a 'street terra' budget line which is probably what you ran into, these come in a Yella Terra box (or at least used to) so people think they are the higher end parts.

Nope. They were their “race” rockers for 18 degree chevy heads. So whatever that was in 2001.
