Ultra Pro Magnum Shaft Rockers????

[T-N-T]

Is anyone using the new design that uses ball-ball pushrods? How is the quality/durability?

I see they come with a 7.550" pushrod when they are sold in kit form. Isn't 7.5" a stock pushrod?

Any idea if they will fit under some old school M/T valve covers?
