Anyone recognize what brand these rockers arms are and what they fit? I got them with some other big block engine parts. Someone had a tag on them that said 1964 413 but from the little research I did 413 didn’t come with this style rocker arm. I’m assuming these fit all big blocks except a hemi but what brand are they? They only stamping I see on them are 871 and 872.

Early factory BB adjustable rocker arms. There good stuff, I'd use them if you have a use for them. 65'
 
IF..... that is an original factory matched set of parts that came off a factory assembled engine....... My guess would be they are from a 64 426MW.

The earlier heads used the bolt on rocker stands.

Looks like a few aren’t positioned in the right places though.
The oil holes should be pointed towards each other.

I just went and looked and there were 2 that weren't in the correct position. There is a set of 16 correct rockers. Any idea what this set is worth on the market today?
 
I just bought a set new for $70 at a machine shop that had them . I bought them for the adjusters to install in Small block rockers. The newer mopar rockers have allen head 3/8 24 adjusters with nuts. The older 426 max wedge have screw driver slot 5/16 24 adjusters with nuts. They are worth the adjusters or to someone building a 426 and wanting 5/16 adjusters. Most builders want the heavier adjusters with allens. They can be drilled and tapped to the larger adjusters.

They are worth between $250 and $350 if they are not gauled. Then they would have to be bushed and it gets pricey.

They should have springs in between the rocker pairs. Those look to be standard BB hydraulic rocker spacers instead.

No, The factory adjustables had spacers. The crane had springs

Not what I have seen, I have a couple sets of original Big Block Chrysler and one set of Isky adjustable rockers. They all have springs. I even have a NOS set of Chrysler springs. Chrysler usually used a single spacer instead of stacked spacers. That being said, I don't like springs and will be using spacers on the 383 when I build it this summer.
