Time for a valve job, maybe some better valves too? Are the factory X valves SS and do they have bronze guides?

Low compression = Moar boost = No more problem :)

Heh, I did that already, see fall dyno day thread :)

Hell yes!

Yea, thats the plan. Gonna get through the holidays and then rip the head off and try to get it fixed asap. The head already has supertech +1mm valves in it, not sure they'd be not good enough...

Supertechs are nice ones. They have been solid for me, I have the same ones and those have been through two motors on my car. I don't think quality or durability is the problem, at least with the valves, maybe another weak point?

Supertechs.

I was going to do Manley's with my build but for whatever reason the Manley ones for the 4b11 are not "manly" and couldn't support the lift on my cams.

edit: sorry for going OT.

Scheides what springs do you have again? Maybe that is your issue? I doubt it though.

I think his are the same as yours; that was my initial hypothesis.
