I have a set of very copper colored roller rockers that don't have any identifying marks on them. They are aluminum and have a rolelr on the tip and fulcrum. I can post pictures soon. How can I tell if they will fit on my stock heads? There are two different sizes for rockers correct? I have done many things with our cars but not rockers. I dont want to pop off a valve cover just to find out and take somthing apart that I can't torque back down right when I go to put it back etc. it is my daily driver... I will have a shop or mechanic install the rockers if they fit. I am also missing two of the little hex/lock nuts that they come with. I have 14 and need a set of 16. Could these nuts be the size of the stud or how do I tell if these fit stock? thanks guys. - kurt


I bought them from ym next door neighbor and he said they are 1.6 ratio and will fit stock but I have to make sure and get the right locking nut replacement for the two I am missing and I dont even know what type of rockers they are..

 

measure the inner diameter of the nut, theyll be either 7/16 or 3/8. if theyre 3/8ths theyll fit the stock stud, otherwise youll have to pay the 35$ for a set of new studs.

if you look around on jegs i saw some very copper rockers there, and if theyre full rollers theyre probably pretty nice (those go for around 380 if i remember right)

also, through jegs you can get 2 new nuts.. i just had to do the exact same thing today

 

irish you rock haha I Just figuerd out they are harland sharp.. I will measure the nut tomorrow and figure it out. thanks a lot bro. btw What is the deal with the studs? Are they screw in style and youhave to buy diff. size and thread them in when doing the rockers? I dont know how it works honestly. I couldn't find a tech article either..

 

okay using a ruler I tried to measure the inner diameter and if I start at the beginning of the ruler and count 7 /16 of an inch it goes outside the diameter of the nut by about 2 notches and the 3/8ths comes much closer. I think they are 3/8..
