Hi all,

I need to buy the set of studs and nuts that hold on the rocker assembly. There's 4 studs and nuts in total. Not the head studs, but the other ones, closer toward the front of the engine.

I've looked on the Minispares website and it says...

"Two long (51K885) and two short (CHS522) per head. course thread cylinder head end and UNF for nut other end."

Why two different lengths? And what size thread is the UNF nut? The two studs its refferring to is...

Any ideas?

the nuts used on the studs are 5/16unf, the course end that threads into the block is 5/16 UNC, so 4 new 5/16UNF nuts is what you will need to secure the rocker shaft to the head

Excellent, thanks!!

Any idea why the different lengths?

short ones for the rockers under the cover. Two long ones for the rocker cover nuts or handles.
