Has anyone used 440 Source roller rockers? Have to buy a set and someone had mentioned these to me and I don’t know anyone using them. Have to buy them for Edelbrock heads I have because they require them. Thsnks

I believe the 440 source roller rockers still use needle bearings on the main shaft which can be bad news. Some have posted stories of the needle bearings letting go sending needles through the engine and trashing the rocker shafts. Other rockers use a bushing instead. Yes I know harland sharps use needle bearings but I believe they are a caged bearing.

They are not reliable

The best cheap rocker is the Stainless PRW and they leave a LOT to be desired
The studs sent with them should go right in the trash use bolts --and it takes a half a day to get the spacing correct where you have roller near centered over valve tip and push rod not rubbing--they are not great but
they will stay in there and run a while on a street unit

There are NO decent rockers for decent price

The Mancini units which are not needle bearing are great except they have a china grade adjuster that you have to be careful with If these had decent quality adjusters they would be good

Harlands are your best bet but they have soared in price and are for a serious build

Just a damn shame we can't get decent rockers for under $400 a set--shoot ...make that $350
I get wonderful quality for Fords or Chevys for around $235 that will stand race roller pressures
It is a real crime!1

the Mancinis could be the answer if they would up the adjuster quality and to be fair I have not bought a set in a long while so ...maybe they have

Do not use them.

If it were me I would get Crane or Hughes.

Call Mike at B3 racing engines and let him help you.


And no, he doesn't pay me, nor do I get kickbacks from him (because if I did, I had enough money to go to some tropical island where there is no internet).

They are made of the proper alloy and heat treat. The draw back is the needle bearings. Don't use on anything but low spring pressure street motor.

Best option for the money IMHO.

Edelbrock heads do not require special rocker arms. You can use factory rocker arms with a mild flat tappet cam. For a fairly mild engine the next step up from factory stuff would be a set of nodular rocker arms. They are harder to find these days but sometimes you can round up a set of Crane or Isky nodulars. Next up from them would probably be the Comp steel rockers or perhaps the Mancini aluminum ones. Hughes makes a decent mid-price set and then you start to pay more for the Harland and T&D and stuff like that.

Do not buy them. I had the adjuster bolts break off of 4 of them and they were not to tight. One broke off after valve lash was set with the valve cover off. That was a new set last year.

I have since bought a set of T&D's for mine, but out of all the valve train parts that failed on my engine the 440 source rockers still look like new after 4300 HARD miles, oh well they are in the trash now. valve springs 155 seat,390 open

The mancini rockers are now made by Harland Sharp. Nice rockers for the price.

I hope your running a fine screen pick up or inline oil filter to catch those needle bearings before they stop your oil pump

If they all failed, they would not still be sold.
The idea is "will the ones that I buy fail?" and the answer is "we don't know".
Considering the damage (needles loose in the head may break everything, even if they don't reach the sump): how good are your nerves?

I dont run BB stuff but if the big problem
seems to be the adjusters you can buy a quality
set of adjusters from a few different places.. as
for the needles I run a screen in the valley
and up the sides so nothing gets past.. I run
TDs on all my junk.. this is just a idea if you
wanted to try it
