Im fixing to do a build with an ls3 top end and was wondering if the ls1 and the ls3 rocker arm stands were the same. I have a buch of ls1 rockers and stands. I know the ls3 intake rockers are offset but are the stands the same?

 

Not the same

Exhaust rockers should work, and as you mentioned, the intakes are different. The LS3 heads don't need the stands, they feature is cast and machined into the head.

 

Scratch that.. total brain fart. LS7 head have the cast in bosses, LS3 heads still need stands.


You can use the LS1 rockers on the exhaust side, my brain says you can't use the rocker stands. The rockers bolt down in the different places, the offset is from the pushrod to the fulcrum.
Lemme do a quick PN check.. From Service parts website. There may be older PN's for these parts, but these are the latest ones.

Exhaust rocker arm is the same - 10214664

stands, aka rocker arm support - 12552203 all catherdral port heads.

Rectangle port, L92 LS3 L76 L99 L96 yadda yadda.. 12600936

HTH..
