NVH is subjective. Most people love their Hooker Headers. I believe the only place for headers are in the scrap metal dumpster. Does a 2.2 vibrate more than a 2.5 with the balance shafts? Manufacturing tolerances?

I'm about to throw a wrench into the works. Today I replace the right side motor mount. The old mount was installed in the incorrect direction. That's how it was when I removed it from the 89 Shelby. I replaced it with a Anchor 2600 mount and installed it in the Gary Donovan recommended position. Well the hood wouldn't close. The drip tray under hood louvers was hitting the valve cover and removing the 1/4 inch was no help. So I reinstalled the mount in the incorrect direction and then replaced the other two. I'm not concerned, the car drives fine, I just figured I pass this along.

.. hitting the valve cover or your TII intake
84-86 turbo z and lazer with the vented hood require removal of the dribble pan to clear the intake .. everytime
- and , if your wireing at the rear of the motor is in fair condition you don't need the dribble pan anyway
rain , no prob
packed full of snow under hood .. still no problem
and yes it will fill with snow on top of the intake lol
The top of the valve cover is parallel with the top radiator support, so l'm guessing it's level. I'm using a one piece intake manifold. The only thing that was removed was a little spout riveted to the drip tray. I recently installed a Tll engine into my friend's 86 Daytona Turbo Z with a two piece intake manifold and only need to remove the spout to get the hood to close on his car.
It was hitting the valve cover. I only drive the Daytona in good weather, I have another vehicle for that. But regardless I like having every shield and cover in place, even if they seem insignificant.
I just looked at my phone's pictures of my friends engine install. I basically pulled everything off his original engine and bolted it to the Tll engine. His R/S motor mount is orientated like mine.

That pic blown up sure looks like the cradle is on top of the mount and it's just bulged from sag at the bottom. The drip tray shouldn't hit the VC, The VC is in the same spot on a suckthrough motor as it is on a blowthrough setup.
