Accidently bent closed valve with mallot.

Accidently bent closed valve with mallot.
I was removing my valve springs to do a cam swap on my 383 when one stubborn valve lock wedged itself in the retainer wrong and wouldnt come out. Eventually the lock stripped its self off when i pulled it and beat on it(was STILL very stuck in the retaineralso needless to say I went with a new spring). In the process i bent the valve very slightly. It will now open comfortably within the lift range of the cam (.515 with 1.6 rockers) but beyond that it gets stuck in the guide. My question is could I just tap it back into place the same way I bent it and run it? Or will i need a machine shop to work on it?

Re: Accidently bent closed valve with mallot.
I think you already know the answer and are just looking for someone to help you rationalize what you have already decided to do instead.

Re: Accidently bent closed valve with mallot.
yeah, bend that biotch back into shape and run it. Then check back here on how to rebuild it the right way.
C'mon......you know the answer.

Re: Accidently bent closed valve with mallot.
Id slap it in my valve machine and and see how un-true it is. It depends on where the bend is. If its right under the head of the valve, some ppl will straighten it as good as they can, and then grind the face true so it will lay flat on the seat.
HOWEVER, valves are cheap.
maybe think about, do you want to upgrade to nicer valves? What type of heads? is it worth it?
If you are on a budget, I cant imagine a shop charging more than the price of a new valve to straighten it... Depends on valve type, shop and how busy they are.

Well heck, spin her up fast and get her good and hot and she will straighten out fine!! Dont pay any attention to the smoke or metal grinding on metal noise. It will eventually stop. Come to a screeching hult actually. Then you know she is fixed.

Re: Accidently bent closed valve with mallot.
The valve lock had dug itself into the retainer pretty hard it only came out after hours of work. What the h*** was I supposed to do? Anyway I took it to a local shop and he said he would cut it off, get a new valve and do a good valve job on it.
I was hoping I could cut a corner here because I start college next monday and this is my ONLY ride there and to work. I guess missing the first few days couldn't hurt.

Re: Accidently bent closed valve with mallot.
most shops lay the head on a table with a thick rag under the head incase the valve does come off the seat . then they place a socket over the retainer and give it a whack with a hammer and the locks pop out , theres nothing wrong with doing it this way unless u have some really stiff valve springs

Re: Accidently bent closed valve with mallot.
His first post? Yeah he screwed up. It happens. He obviously hit it at an angle, not straight on. He owned his mistake.
I used to change springs a lot when I bracket raced. Heck, I wrote the spring math for dummies post back in 2004.

I get to argue. We encourage solid tech debates.
