Rocker arms

Those are probably overkill for what you are doing. As I recall, Comp does a stamped rocker with roller tip that is reasonably inexpensive and would be all the improvement you need. They are available in different ratios.

I think you need to clarify if you have a 3.4 or a 3400, most people in the 60/6 world refer to these engines the way the factory labelled them to differentiate the various versions, 3.4 means RWD gen 1 engine, 3400 is the fwd variant with aluminum heads, with a 3.4 dohc being fairly obvious, sometimes people specify 3.4 rwd to clarify, and not everyone refers to the 3.4 dohc as dohc, some just call it a 3.4.....
Anyways, lighter rockers is a good thing even if the ratio is the same, full roller is also better than just roller fulcrum, what all of this means is less rotational weight(yes they are not technically rotating, but bouncing back and forth makes lightweight more important if anything) and less friction=more efficiency=more power, also I would go with the comp ones just cause they are cheaper, I actually plan to get those when I do my 3500 hybrid buildup.
On a side note I have always wondered, why does nobody make higher than 1.6 ratio rockers for the 6/60, is it because it would be too much valve lift and cause piston/valve interference or what??

We're basically too small of a market to have anyone make us a set. There were 2 companies looking into it at one point (up to 1.8:1 no less!)...but that was before the recession hit.

As for the Crane Gold rockers. Didn't Aaron run into issues with them showing metal flakes coming out of the fulcrum roller?

3400 and idk i haven't heard anything about whether or not his setup was working or not. I just keep hearing that you just need to make space for the lim for the gold cranes to work i'm not exactly sure what needs to be done or who does it but they aren't just drop in replacements

You can see pictures in the threads posted above. Its easy to do you just need a die grinder.

I remember that post.

Found it!

Ah the pursuit for roller rockers greater then 1.6:1

Someone had a set of HS and ground down a few of them to fit. Can one actually grind more material from one rocker versus another with out creating valvtrain inbalance issue?

And how about different ratios between intake and exhaust? Like 1.6 rockers on intakes and 1.5 rockers on exhaust. Don't know why but it seems it may have a use.

One more question...Is there any performance benefit locking the lifters so the do not compress as much? Or would that starve the top end for oil?

It seems if the lifters were locked up the valves would open sooner and close later during.

These may be silly questions but we all gotta learn sometime.
