My 440source rockers are fkt!! I am looking for recommendations with a rocker arm that is bushed instead of needle bearings

Ok with rpm heads?

 

[Chryco Psycho]

I never use RPM heads , there are better heads for less $$ but RPM uses std rockers so it should be fine

I chose Hughes rockers with the Trickflow 240 heads on the last bb stroker build. Really like em. I’ve ran the 440 source in the past without failure but, prefer bushed.

I have a set of 1.6 ratio for my 340. They are pretty well regarded. Can't comment on the fitment on BB heads but most of the aftermarket SBM heads need some geometry correction. That's the result of longer valve stems and fatter springs most of the time. Not a huge deal but something to be aware of. Optimizing geometry with roller rockers goes a long way towards reliability and maximizing lift.

I can't comment on how durable those rockers are since I don't have the car back together, but the 1.5 ratio fit well on a set of 440 Source heads, with a very acceptable sweep across the valve stem with no correction kit installed.

Which 440 Source Rockers did you use? Hopefully not aluminum!! I ask because 440 Source actually listens to us consumers and try to make their products better. Their original stealth heads are much better now than when they first came out with them years ago. It would be worthwhile to provide some feedback to 440 Source.

You cannot go wrong with Hughes Engines rocker arm kits. Their standard offset rocker kits fit most of the aluminum aftermarket heads.

I used these with my Trickflow 240 heads on my 383. 1.5 ratio.

The 440source aluminum roller tip and needle bearings is what’s on this engine. Plenty of scarring on the shaft and few flattened out needle bearings.
I hope the prw 3244012 ones are better bc I am reading a few negative reviews with seized bearings and a gritty feeling, also a lot of grit/dist coming out of them on prewash.

You definitely want to take the rockers apart and clean them and run a piece of wire through each orifice and flush the shafts out. My rockers had a few chips in them, which doesn't surprise me. The hand work required to thoroughly clean them adds cost and I'd rather do it myself to save and make sure it is done right. I also chase the threads. I would do that with any part going in the motor. Trust, but verify.

Ya it’s too bad I didn’t see they won’t work on my future upgrade to the TF 240’s

THIS is exactly why I never use needle bag rockers , only 3-4 carry all the load & don't move very far grooving the shaft & wearing the needle bags , Bushed rockers are far better as there is so much more surface area to carry the load

 

[Xcudame]

Agreed, needle bearing rockers are the most likely to fail. And aluminum rockers are great for a high revving race engine that will be torn down frequently, but I'd never use aluminum rockerarms for a street engine. Aluminum doesn't have the fatigue strength that iron and steel have!

I'm using hughes and their shafts
