Has anyone used these?

Do they really produce a benefit?

Can you run them on a wet sump system?

Will the motor use more oil or smoke due to excess oil passing the valve stem seals?

I am looking to turn more RPM's than one probably should on the street and trying to maximize the life of the valve train components as much as possible.

Any input is appreciated.

 

They are not needed unless ya have blocked the normal way of oiling the top end.

 

Thanks for the input.

Why would you blcok the normal way of oiling the top end?? Are you talking about cam galley restrictors?
