Will these work? https://www.edelbrock.com/pushrod-guide-plate-for-amc-9669.html

Other options?  Going with scorpion rollers in my build. https://www.summitracing.com/parts/scc-scp1054 Not sure if the studs are included, so thinking about ARP studs. Any recommendations?

84 AMC 360 Should be 64cc heads.


Thanks.

You may need to machine the top of the rocker stud mounts (pedestals). These plates are 1/8 to 3/16 inch thick, can't remember.  All depends on pushrod and rocker geometry.

are you working with 291C heads?

On a 1984 360 head, to use those rockers you will need to machine the pedestals ~ .375" and use guide plates.  The stud holes in the head will need to be drilled and tapped to 7/16".  You will probably need a custom or different length pushrod and need to buy the studs.  By the time you're all-in, look at Harland-Sharp rockers that are a bolt-in.

Does Scorpion also offer bolt-in Roller Rockers for the bridged rocker AMC heads ?

Those are not the guide plates to use.

Here are the guide plates you want to use since they are made correct for AMC special needs.

They also allow you to access the head bolts with out having to remove the guide plates.

I don't know but I like the H-S rockers on my 4.0....... which had bridged rockers.
Other than needing to shim up the pedestals because I shaved the head a fair amount, changed cam and so on and wanted the correct lifter preload and valve stem contact, they simply bolted on.

Don't have much experience with guide plates (coming from a Mopar), but here is what was being used in my 304 stocker motor:

Others will work, but I agree with PROSTOCKTOM, and using the Performance American Style type.
Understanding is they are made in Texas using American made materials.
