Anyone Running Turned Down LS3 Valves
Anyone Running Turned Down LS3 Valves Trying to spec out some heads and spoke with Mike at TEA and he can turn down LS3 valves as a hollow stem option because Ferrea does not offer a 2.080" with correct valve stem length.
Has anyone pulled the valve after running for awhile and checked the valve seat? I'm curious because seats are hardened for fatigue toughness and wondered if anyone could comment on the durability.
The other option is go with the 245cc head which uses a 2.100" valve and Ferrea does make this valve in the required length. What is the min bore dia on the 245 head?

stability. If anything the valvejob and seats should last longer because there
is less valve bounce with the lighter hollow stems. The 245 heads are prob-
ably meant for larger engines having a bore size of 4.065"-4.125"
Here's a cool part I stumbled across when considering valves/sizing what not

The 245 is what I'd run. I wouldn't even think twice about that on a 4.125" bore.
If you want more than 600rwhp I'd go LS7. But for 600rwhp + torque the 245s are my choice.

is just a dinner plate in the way of flow which is why most head gurus try to
get the most flow possible from the smallest valve.
Sure, why not?
Yeah, it's just in the way of flow. Like the heart just pumps blood throughout your body. Why wouldn't you want to biggest valve possible/reasonable?
