valve bent?

RE: valve bent?
It sort of depends on the situation... what makes you think the valve is bent?
use compressed air... if you hear air "wooshing" in the intake or exhaust with shop air "pressurizing" the cylinder, it my indicate that the valve isnt seating correctly, so It doest seal entirely.
We really need more information though

A vacuum gauge can tell you if you have burned or bent valves.It' been awhile since I had to use one but a lower than normal vacuum with a fluctuating needle is a bad sign.You can hook the guage to just about any vacuum fitting behind the throttle plate to get the needed high vacuum for the test.
The individual pressure test will show which cylinder.If the engine was running at high RPM when the damage occured,don't be surprised to find more than one and maybe all the valves bent.If it was bent because of a sticking valve guide it's probably limited to one cylinder.
