What ones are they?
They say PATD on them i think, cant quite remember.
Standard pressed steel rockers
About 1:1.21-1.25 ratio.
The later sintered rockers tend to wear where they tip on the valve stem,
making it hard to set correct valve clearance.
That’s why I, personly, prefere this pressed steel type rockers
Excellent, going to get some 1.5s for my 1380, these are worn quite a bit on the ends aswell.
Will I have a problem with a kent 286 cam and 1.5 ratio rockers?

I hope not, thats what im running!!
these look a like a set of 1.29’s i have just fitted to a friends 998
They are standard older a-series arms. If the pad faces that contact the valves are “round” they are from a small bore engine. If the pad faces are oval they may be from an Austin America or similar (1275) variant. They are not bad rockers according to Vizard. However, on higher performance engines I believe he calls for additional tack welding of the pressed steel parts to make sure they stay together.
looks a bit like these…
