Put a little anti-sieze on the threads before you install the plugs.

The tried & true way to clean your intakes (Al, chime in anytime :D) is to use the SPRAY GM top engine cleaner. It is not available in all states, but if you do a search here you will find that there are some members willing to buy and ship to you if you cover their costs. IMHO seafoam also works, but it won't remove heavy deposits like the GM cleaner. It's better as a gas additive to keep the top end clean.

Cool, whats the procedure for using that top end spray?

Idle the engine, spray the spray directly into the throttle bodies until the gunk is gone. Only takes a few seconds of spray if there are light deposits. Engine may rev and/or stumble and you'll see some smoke from the exhaust during this - which is normal.

I'd use a few drops of oil or moly lube on the threads. Never sieze around a spark plug can be problematic. It can be used but it only takes a little.

Here's what Autolite says about using anti-seize (snicked off the net somewhere):

We do not recommend the use of any anti seize products for installing spark plugs. Anti seize compounds are typically composed of metallic,
electrically conductive ingredients. If anti seize compounds come in
contact with the core nose of the plugs, it can lead to a misfire condition.
Anti seize compounds can also have a torque multiplying effect when
installing plugs. This can lead to thread distortion and thread galling
resulting in cylinder head damage. Autolite spark plugs are nickel plated
to resist the effects of corrosion and seizing. However, plug seizure is
aggravated further when steel plugs are installed into aluminum cylinder
heads for a long period of time.

Great in Chevys too, and it pains me to admit that!

But seriously, the graphite in anti seize can cause problems.

Ever take a graphite pencil and make marks inside an old school distributor?!

:D
