Pull the valve covers and you will likely find whatever it is right in front of you.

Unplug the the spark plug wires from the coil packs, uplug the coil main harness, 10mm bolts on the valve covers. Then 8mm bolts to remove the rocker assemblys. Now you just pull out the push rods to inspect them. It's not to bad...
If that's what it is, I might have some laying around. I will mail a couple, if I can find them !!!

Ya, The stock valve springs & push rods are the weak link... It's real easy to float out the valves, causing bent valves too... After I bent a few, I installed comp cam bee hive springs & magnum rods.

The block is most likely fine ! I ran my stock bottom w/ a big cam & a 150 dry shot for 4 years !!! That motor got me into the high 10's !
Actually, I got on ebay and bought a block & crank for a future build, "but", I popped my motor & am rushing the new build now !!! I'm hoping my old block is OK for a spare build !!!

9k and we might be talking new motor! 6 liter here we come!!
Anything above 6k makes me nervous on a street motor, Well, except for a bike maybe.
That thing must be humming crossing the line at 7k. And sounds good too, I bet !

That is pretty close to the sound mine makes, but no bent pushrods or broken rockers or valve springs for me...I'm 99.9% sure it's a lifter in my case cause I've already eliminated all of the other valvetrain variables. My car used to make the sound only as rpms increased, but now it does so at all rpms and idle, and it's starting to miss a little.
Definately pull the valve covers and take a look!
