I think I remember the stockers as having valve reliefs also.

Just put new rings in my early 86 and it has flat top Hyper-pistons with the standard four valve reliefs in them. Hope this helps.

1984 and 1985 used the same pistons. And yes, the were forged for those 2 years.

RACE ON!!!

Interesting... and true. I was not aware that GM did this so I looked it up. I wonder why they went from forged on those two years to cast pistons that acually weigh more on cars that are supposed to be increasing power?
