Default Still Looking for LS7 Valves

Any established sources yet for stainless valves? Also, does anyone know the overall length of the LS7 valves...
Thanks

I am too interested in this. I heard SS valves for LS7 heads will be too heavy, but still curious to if it can be done.

I think Andy at A&A is having some custom made. I believe he actually has some installed and running with good results, but don't quote me. Give him a call, he might be able to help.

Almost correct. The engine will be running this week as the heads were just delivered. We're going to be making a run of valves this week as we have a number of sets of heads left to assemble. The valves we installed require sleeving the guides down to the fractional (5/16") stem size.
We can also fit the LS7 heads for Jesel rockers for those who would like to upgrade.

We are using 5/16" inserts also.

How much for the Jesel conversion? I want to do this to my LX7 Warhawk heads when I get them.

I haven't had any Warhawk components in here yet so I don't know what I'm facing. The cost to machine the LS7 heads for the Jesel rockers runs $150.00 per pair. The supplied Jesel saddle bar mounting studs need to be shortened to fit the heads. If we have to modify the studs it'll run an extra $100.00 per pair.

Default LS7 GM Valves

FYI, GM says about 3 more weeks before the release of the factory valves.

Are there any worries about LS7 titanium valves having problems taking a 150-200hp nitrous shot with the proper tune?

No problem at all. You have to remember that the badest Pro Mod engines in the world run titanium intake and exhaust valves and spray more NOS than you could imagine. They are top of the line quality and will have no problems with the right tuneup.

I should have waited a few hours to post. We just got in the first set of LS7 intake valves. They were already sold but that is a good sign that we will see them sooner than originally thought.

The intake valves are titanium and the exhaust valves are sodium filled steel.

What are the stem sizes and lengths? What about seats and guides? What type of locks do they take?
