I had my eye on those valve covers but it sounds like they are slightly headache inducing due to their raised height qualities that they advertise them for, which is a bit of a bummer. Plus the more I think about it the more they would draw the eye of a smog tech inspecting the vehicle come inspection time.

I agree, I think the JMS has a ceiling of somewhere around mid 700's. I'm seeing mine start to ever so slightly drop pressure up very top but it's not anything that worries me.

I'm gonna message you so we can exchange information!

Thanks Rob, just emailed you... as for the valve covers, I agree... wish the baffling was there, but they have not been an issue for me, the restrictor + MM wild CC work well together.
