I'm gathering up a list for a bigger build.

S467
180hp 78% overs
10M CP3
Doc's band-aid
I was thinking of new springs for the valves for safety assurance.

My question is, I've started researching this mod "new to my knowledge."

There are controversial arguments between people for and against it.

I want some feedback from folks that have or have this installed.

The goals are for 700-750hp.

I would instead buy once then twice.

My S464 has maybe 6k on it that I will be selling when the time comes.

I'll continue to research more.

Thanks, fellas.
