Both heads at the machine shop for a valve job and cleaning. Having them replace the valve stem seals and new springs as well. Should have them back Tuesday. One of my lifters had pitting on the roller, causing the noise.
Fancy AIR block off on those headers! ;)

My buddy had them laying around when I needed the broken exhaust bolts extracted. The Dorman cheater clamps are pure garbage. Couldn't pass them up cause he threw them on for dirt.

I also don't think it's worth the $500-600 in these items for the 10-15 rwhp it will offer me. Unless I'm seeing it all wrong.

$500-$600? Aren't these things just stock GenIV intakes? I've seen complete take-off NNBS manifolds for as little as $40 here. Average is $100-$150. Sure, you might need a particular TB, but that's a salvage yard part, too. Injectors rarely go bad and just get dirty at worst. If you wanna start fresh, a cleaning/refurbing service is $200 or less and they'll be like new with a printout of their test results.
