It's now time to pick valves for my soon to be home ported heads.

I'm not looking to spin things too high, so i don't need super light weight.

I will need some decent heat ability on the exhaust side however.

What valves have people used? I'm staying stock size on the valves, and will be using stock keys and caps.

I've done some digging already, but would like some recommendations

Thanks <img src="gr_grin.gif" border="0">

IRS sells Manley Race Masters for 93 bucks a set (exhaust or intake)

www.racenet.net

I am sure other sponsers could match that price. Summit or Jegs would have them too.

 

Ok

But, are they any better than stock?

Higher strength/temp range than stock?

why are they better?

 

Have you thought about 2.055 intake and 1.60 exhuast. Thats what MTI has been putting in there StageII.

I have heard over the years that Ferrea valves are better than Manley valves.

Why not go titanium you baller. <img src="gr_stretch.gif" border="0">

 

How good are REV Valves, as compared to Manley or Ferrea??

Hope they are good, that's what I got!

Thanks,

Any quality valve will work fine on the Intake.
And upgraded material on the Exhaust is a very smart idea. For long endurance under hight heat and stress, hardly nothing beats Inconel.. especially IN718. If you are sticking with stock size valves, consider the factory '02 LS6 Exhaust valves. Shame on Chevy for trying to pass sodium filled exhaust valves off as something new. They were standard equipment on the 1962 turbocharged Corvair Spyder.

If you have new seats installed on the Exhaust, pay close attention to the isntallation method used. Pressing them in at room temperature just isn't going to cut it on an aluminium headed, turbo engine.

 

From left to right that is Ferrea, Rev, Manley, and 98/00+ stock. I like the Ferrea's personally, but the other two are nice too. Why are you going to use stock valves? If you're on a budget, use the stock (w/back cut) intake valves, and get some aftermarket exaust valves.

If you need anything, just holler.

I'm not too concerned w/ valve sizing at this point. I've made plenty of power on stock valves, and unported heads.

The intake side i figure a nice under cut stem valve will work nicely. Ferrea is what i'm leaning toward. My biggest concern is on the exhaust.

There is an OEM valve that is 23-8N alloy, the next step down from Inconel. And i can get them for about $130 a set.

I don't plan to rev this motor to high hell, so i'm not after super light weight.

Anybody make an inconel valve for us yet?

 

LPE uses Inconel in the Stage 2 TT exhaust valve...I think REV makes it for them.

 

We have pretty much always used Ferrea valves - I would give them a call and see what they have for your application!

We can get the valves for you if you need them Harlan. I would go with the SV duty stuff or the inconel stuff on the exhaust at a minimum and at least SVD on the intake.

Let me know if you need something

Eric, yours have the severe duty intake and exhaust so you are good to go! spool er up!!

 

My heads are currently being done at a local machine shop. My machinist told me that Manley stainless steel valves tend to break because they are brittle, so we went ahead and ordered Ferrea's.

 

Get both <img src="gr_stretch.gif" border="0">

I have Ferrara high temp exhaust valves and Manley intake valves.
