replacement cost

Hi ,i was looking to get a ball park figure as to the cost to have a intake manifold gasket replaced on a 1993 olds 88,3.8 litr? .In a small local auto repair shop .Unsure if its upper or lower but would like price for each.
Thanks!

About 5 hours labor at whatever rate plus any parts/fluids.

$470-$680, depending on labor rate.....more if the upper plenum is developing a hole near the EGR pass through....
