I have been shopping around for some new valves for the LS motor I am building. It is going to have the crower 404 valvtrain with cams, springs and retainers. I am just wondering if anybody on the board has tried KMS`s valves or any other products they have. I personally only have there cam seal but have read some good things about them on HT. Any input would be appreciated.

 

Keep the OEM valves unless you are going oversized. If anything just get them cryo'ed. Also pickup some seats and keepers

 

Is there anywhere I can go to get the valves treated locally? Ir where do I go to ship them out? I remember seeing a flyer about cryo treatment at CFM a long time ago what does it do?

 

Read up about it at http://www.deepfreezecryo.com/process.htm . There is a local company that does it. I just cant find their business card I know the guy has a turbo S2000

 

Thanks for the info. I think I will deffinatly do that to the valves I have. None of the valves on the head I am putting the valvetrain into are bent. Should I still but new valves or would just buying new keepers and seats be ok? BTW do you think the local shop has comprable prices? They were only charging $4 a valve. Thanks.

 

$4.00/valve seems like a good price if the process is done right. Who is doing it for you? I paid a little more than that but not much.

 

The website you gave me witht the info on it had a list of prices for parts to get done. I am going to go to KFM on my next day off and see if I can get the number for the guy who does it locally. thanks for the info much appreciated.

 

I prefer REV

 

Yeah I bought their entire valve train so far so good, but I will see now that I have to take off the head on a 48hundred new motor because of a shop that fucd up and cant fess up to their warranty and the worst thing about it I just got the turbo kit in 5 days earlier, but oh well what can you do ? I will let u know
