Ford 302 roller rockers question.

I was given a brand new set of scorpion roller rockers that say 1.6 and 3/8 on them. Box comes with 16 of them and some other things that would come normally come with this set. I'm wondering if I can install these replacing the old ones or do I have to replace other parts in the valvetrain in order to use these.

I believe that the 3/8 are stud mount so you'll have to install 3/8 studs and possibly guide plates for the pushrods
Did the rockers come with any instructions?
What does the set include?

I don't really know what those black things are but that's all that the box came with, exactly what's on the pic. A friend gave me this set for free so I'm just trying to see if I'm gonna need other parts.

Check the part# to be sure that they are stud mount rockers and if they are, you will need the studs and guide plates to install them.

The black thing is the nut used to adjust them and lock them into place.

Yeah they're stud mounted. So you're saying I'm gonna need a set of 3/8 studs? What else do I need?

Yes they are.
Typically, you need guide plates for the pushrods as well.
The studs and plates are very easy to install.
All of the rest of the valve train components will work with the rocker arms.

That was very nice of your friend to give those to you. Those are good ones!

Thanks. We're building forged internal supercharged set up with hci. Friend said might as well throw in these rockers I've never had a chance to use.

Not sure how you can install Stud Mount Rockers on Pedestal Mount Heads when Stud mounts are 3/8" & Pedestal Mount are 5/16". I was told I had to have pedestal mount so that's what I bought. Good Luck installing those.

I've heard a lot of people say Pro Comp Roller Rockers are crap. I have no idea why as I've used them for over a year now & I know 2 other guys who also use them & none of us have had any issue with them. They're only $170 from Summit.
Anyway, you'll probably want to stay with 1.6 R.R.'s as you'll need taller valve covers if you use 1.7's.

I've had a set of cast aluminum, stud mount, Comp cams roller rockers on my 460 for 410k miles. The pushrod guide inserts weren't changed until 380k miles... And not a moment too soon!
The Comp cams High Energy are probably in the same quality range as Pro Comp but, for most street engines, they should be pretty bulletproof. Hell, I've seen expensive billet aluminum rockers break when run at high RPM's for sustained amounts of time.
The main advantage to using stud mounted rockers is that they are infinitely adjustable without having to monkey around with different push rod lengths and shims. My 460 had so much material removed from the cylinder head and the block deck that installing the stud mounted rockers was easier for me than figuring out the pushrod lengths.
