School me on Stock Eliminator?

heres something interesting:

NHRA SuperStock Legal Cyl.Head Volumes

"302" Intake Max CC 162 Exhaust Max CC 70~ 1.78"/1.50" Valves
"915" Intake Max CC 158 Exhaust Max CC 75~ 2.02"/1.60" Valves

makes yah think about them "tiny" 302 heads eh?
can't find if they are legal on any year Stock or SuperStock engines tho.
