Close , they also have some additives in there to help it hang, Either Cab-o-Sil M5 or EH-5F (same stuff in some milk shake mixes) plus a surfactant to help it wet out.

Acetone is VOC exempt now......funny how it was considered a major Ozone depleting solvent for long time.....(wink, wink ,nudge, nudge,) But now it's all Good I guess Nail polish remover is more important than we realized

I have used them a few times I have a set in a 392 with a Howards .600 lift cam, he's got about 25k miles on it now. , had set on my 428 in the old 2014 truck with the Comp cams 274 XFI camshaft, I put 12k on that before I pulled the 428 and sold it....it now resides in a 72 Road Runner Clone...may another 7-8k mile on it.
One of the guys who works under me has a 05 Magnum which is his daily driver,392in 5.7 build, he has had a set of the PRW PQX(same thing as Procomp) roller tip rockers on this thing since mid-2013 the 1st set broke a roller tip after about 1k , PRW was quick to replace the set , and the 2nd set has gone 40k .ran a Comp Cams 273 for about 35k of the 40 now has a Green racing cam , 59X/58X lift , He also has another 05 maggy with a 2014 Charger clip that he runs in the Hemi Shoot out stuff, 389CI Darton 6.1(4.155X3.59) constantly in the 8k range ,stock DLC coated shafts , Manton collars and hold downs , with a set of the PRW rockers.

Now ...are they over kill, no.....but as long as your old rockers don't have burnt tips...go with what you have.,,,one thing though , have the ends(side that runs against the stand or collar ) checked make sure they are flat some of them have for a lack of better wording have jagged edges.
Stock shafts are plenty good for lifts up to high 500s and 7k RPMs
Collars and hold downs are a good thing if you have the spare cash....If I had to choose I would get collars over the hold downs.
Thanks for the info on these , besides the one roller tip , are there any problems into running the PRW / Pro Comp Roller tip assembly ?
I can't seem to find much info on the shaft they use , ?
Any problems with the pushrods fitting properly ?
thank you

Ow and the rocker assemblies have been in Acetone for 4 hours now , they didn't have any sludge on them, just Dino oil varnish , which is STILL on them ,
may have to try something different ?? I'll give it a couple days see what happens .
What is slightly alarming is that on a couple of the rocker arms , top of the arm part , it did clean them , very strange , not your usual slow transition from dirty to clean , but a hard separation, almost like it flaked off just in a small area, I'll send photo's later , almost like an area of stress ???? photos on way

Here is what I'm talking about :sad:, maybe it's just where it decided to come off first , but it almost like the area's that it is coming off , are high stress area's:eek:

Maybe I'm just full of it , or seeing things that aren't there .:icon_peace:

Anyone seen this ?

That does look a bit different. Can't imagine the chemicals corroding the metal or it being stress related.. sorry IDK...

I'm going to go with Metal is less porous in those spots.

6AM , about 12 hours of soaking ............
Here is closeup of one rocker , with 2 different cleaning patterns ,
Note: the clean area to the right , I circled it in white , it has SOFT cleaning transition ........

Next photo is moving the rocker arm, Note under that area......... an oiling hole.... .... so that area was probably a little cooler running than the rest of the rocker.

But that still doesn't explain the other cleaning pattern ..........

Guess I should have taken ANOTHER year of engineering classes :banghead:
:lol::lol:

Has anyone tried putting banana grooves in the rocker arm shaft for better lubrication ???
I know it a common thing to do on the older generation small block's , and
I know the aftermarket shafts have them , but was curious if anyone tried it on their Gen3 stock shafts ??

thoughts ?

The reason I ask is look at the wear pattern on the shaft below , by the oil hole

I would be afraid they would develop cracks. But not having done this I can't say with certainly they would. The oem wall thickness is only around .187"- .0157"..

Installing Johnson LS style hydraulic lifters.
Proper harmonic balancer fitting/installation on crankshaft.
Clearancing Hemi engine block for stroker crankshaft.
Proper ring gaps for n/a, nos and boosted Hemi engines.
Proper cr for n/a, nos and boosted Hemi engines for street/track.

They did run a die grinder ?(I think) around the sharp edges , nice touch
I especially like the attention to detail with the de-burring. To me it expresses quality and is the way it should be finished...
