Boosted LS1 valve train selection!

[@KSenhor]

Will you make these valves for a EZ30R H6 Subaru engine head?

[@ericsmcmahan]

David Localio, what type of seat materials are u using on this ls head for boosted applications?

[@headgames]

Oem seats

[@gilm3853]

Would there be any benefit to a max effort type engine to have the tooling markes in the chambers softened/polished out?

[@christopherdimotsis1024]

Increased ease of flow is always good but only makes a big difference in NA applications. If your doing forced induction your measurements should be mass flow not volumetric flow. Because when your compressing the gas you can flow the same CFM but higher mass of air and thus you need higher mass of fuel…..

[@jakobsimmons9997]

Most of what you said is true. Ease of flow can make pretty big differences even in boosted applications. Especially when it comes to reducing strain on components, more airflow=less boost psi=lower temps..

[@V8Lenny]

When boosted the gain you get NA is multiplied by boost pressure ratio, so it is even more important with boost.

[@chriswise1232]

What's the weight difference?

[@GriffonGrowl]

What degrof tulip do you use on exhaust valves

[@FadetoBlack1463]

.115 away from coil bind its a bit excessive no? Wont that cause spring surge?

[@headgames]

nope the call out for the spring is much more than .115

[@FadetoBlack1463]

@@headgames The "call out" what does that mean?

[@levanmotsonelidze6676]

It's Dyno tested proven - tulip type intake valves make less power! (Not talking about boosted applications) P.S. static flow numbers are not always translated into the horse power

[@headgames]

We don’t use a tulip on the intake

[@levanmotsonelidze6676]

My apologies. Good luck!

[@V8Lenny]

It is also dynoproven that they make more power, depends what application.
