I got new trickflow rocker arm studs from a friend....how do i tell watsize they are?

 

If the diameter top and bottom is the same they are 7/16" if the tops are a smaller diameter they are 3/8. The part that screws into the head is 7/16 but stock studs and stock replacements neck down to 3/8", when we upgrade it is just that tophalf that is larger and is then the same diameter as the bottom.

 

I'm gonna go out on a limb here and say you should measure them.

 

no thats ok the other guy helpd me out.

 

lol, one would think, but i guess he got it figured out
