We installed stainless works on a truck recently. Starter had to come out, engine had to be tilted a little bit, and the motor mount on the drivers side had to come off (only because of a heat shield in the way which we knocked off for future ease of uninstallation and reinstallation.

took about 3.5 hours.

You will need to take the a/c compressor bolts out - let it hang.

if doing on jack stands use a floor jack to raise hand lower the motor/transmission to get the headers in and the ypipe in and out.

So is the general consensus still to use stock studs and bolts if possible? Is false knock from stage 8 fasteners a common issue?
Curious on your inputs.

if you unbolt the motor mounts and raise the engine you can use the factory studs.

I did it with out loosing the motor mounts, so I had to use the stage 8 bolts.

On next set I do I will not use the locks just the bolts.

false knock is a nightmare you donít ever want.

And the stage 8 locks are a common problem on all modern engines

I didn't think about using the stage 8 bolts without the locks. May try that..

Honestly donít think you will end up with a bolt coming loose as these engines are balanced good enough to run 7500-8000 rpm in stock form

General consensus is to use the stock gasket and bolts

the stage 8 seem to be tripping knock sensors for everyone

Just got the Kooks headers with green cats installed today. I'm noticing a weird "whistling" sound around 3k rpms. It's quiet at idle.
Any idea's what it could be?

I would also assume an exhaust leak potentially. I have Kooks headers and JLT cai. After the header install the whistle/sound from the cai was a little more pronounced.

It almost sounds like tire squeal. Except I wasn't spinning.
Will have to take a look tomorrow for leaks.
