Are rocker arms interchangable?

[wiking]

Hey guys!
Once again I have to turn to you for advice. The question is: Is the rockerarms identical on a 302 and a 351? Am about to order parts, but I`m only able to get 302`s. Will they fit on my 351 cleveland? The lift ought to be the same.

:OT: And now that I am here anyway: Thanks for all helpfull and serious answers I have gotten so far! You guys make things a lot more easy for us, who are not blessed with tons of experience (yet!) :OT:

Id imagine so.

Rockers

351c's use 1.73 rocker ratio, otherwise they look the same.

I dont think the length from the stud to the tip is the same. Or overall length for that matter..

Just ordered them. Guess I`ll have to wait and see...
The clever idea was, that when the heads are interchangable, the arms wouldt be too. But on second thought, this in fact does not neccesarely mean the the valves are placed with the same distance to the pushrods.
