You should be fine with the supplied valves at 15 psi.

You can run more timing with the LS9 heads.

well since everyone will return, i am really getting puzzled over the lsx-ls9 ..there is no mention on gmpp as this part...scoggin dickey and a couple others claim they are lsx-ls9 6 bolt heads...here is quick info on the lsx -ls9.then below is the lsx-ls3, which only thing i see different is the titanium valves and exhaust valves...??????? what am i missing??? does the intake valves and exhaust valves justify 200.00 difference per head...is that the only diff between ls3 and ls9 head? . lsx-ls9 L92 style rectangle port design

What kind of rockers are you using mike?

[mikepage0007]

GM LS7 Int/Exh rockers
GM LS7 rocker studs

[JLE58]

The Valves are a good upgrade with a supercharged app. I thought the ls9's had the same valve size as the ls7 and used the same lash caps but I guess I was wrong. I would just buy the ls3's.
