crane 25759-12 , the -12 denotes 6cyl application,i missplaced my invoice. i think i got mine from jegs (then i learned summit is usually cheaper). let them know what its for they might know what your talking about but that part number is off my box. you get the rockers, and the kool nuts with locking setscrews, and your instructions. it says something in the instructions about rocker arm studs from the aluminu heads being bottleneck, or something, and you need straight shank ones from the iron heads. im pretty sure the kit came with them, since the nuts were there, might aswell match them up, but dont quote me on that, like i said i lost my invoice.
like i mentioned befor, i dont think these will work with the 3x00 heads unless you do some machining first and screww in the studs. i seem to remember my 3100 project heads have a pedestal mount thing where the bolt goes through the rocker pivot and it is torqured down.
i just checked summit, they list them online: CRN-25759-12 Rocker Arms Gold Race Chevrolet V-6 80-94 2.8L/3.1L 1.6 Ratio 3/8" Stud
$324.39 but the studs ar listed seperatly, never hurts to call and ask ?'s. try jegs too, i dont remember ordering the studs seperatley. ask ask ask, its waht ?'s are for
