Are the accessory mounts the same on pre '87 heads and '87+ heads?
Basically what is says, are the accessory mounts the same on both sets of heads? If so that would make the only differences the centerbolt and perimeter bolt valve cover setups and the angle of the middle bolts for the intake manifold right?
I want to know if I build a motor with the Stealth Ram could I get pre '87 heads and still mount my current serpentine accessory setup from my '90 motor? Thanks.

The actual accessories are differentt, but the bolt holes to mount them should be the same from the early '70's on up.
You're correct, 87 and some 86's, up up, use the newwer style angles...could be that the HSR is ready for both???? Not sure, by Accel Base works for either (Accel claims)

youll need to drill + tap one hole on the pass side head to accomodate the bracket. Otherwise, you good to go.
