exhaust valve

hello i have a 91 honda prelude b21a1 DOHC and its been running like shit for awhile i took it in and got a DYNO and it shows that cylinder 1 2 and 4 are firing with minimal leakage but cylinder 3 has 85% and they said its my exhaust valve isnt closing and was wondering if anyone knew how much it would cost to get one and how hard it is to replace

bent valves? those are expensive.

I think the list price for them through a dealership is around $30 a piece. Other places might have them cheaper than that though..

This place has them for 15 and change:

Select your vehicle, then engine mechanical, then exhaust valves.
