I have the intake and it is very nice. A Holley Sniper 92 mm LS cable operated throttle body bolts right up. That's a big plus. And the intake comes with really nice fuel rails for $585. Putting the heads and intake on this weekend.
I've heard mixed reviews on the valve covers, but a lot of people will complain if there ice cream is too cold. Myself... I'm thrilled a big company like Holley is making this stuff for us.
