Don't sweat it too much,
Even if the threads are totally ruined, you can helicoil it for cheap.

FYI use a torque wrench to install the new plugs.
EDIT:

Spark Plugs (Cylinder Heads-New) 15 lb /ft

Spark Plugs (all Subsequent Installations) 11 lb /ft

Spark plugs ARENT in the block. They are in the heads. You may have already screwed up and pushing shavings into the cylinder, for your sake I hope you didnt.

arnt the heads aluminum, i can't remember if aluminum is magnetic or not. I would try blowing it out with a air compressor.

Heads are made of aluminum and no a magnet will not work. Are you serious about blowing it out with compressed air? Blowing metal shavings into the cylinder sounds like a real good idea

You need a thread chaser! Go to an auto parts store and get one before its to late.

wouldnt i have to pull the engine to helicoil it? what is helicoiling it anyways? im pretty sure 11ft/lbs isnt much weight am i right? i get probably about hald the plug in there and it gets extremely hard to turn so i stop. i wil try to dielectric compound...i checked the shavings i pulled out eaerlier and they are magnetic so it sounds like a piston ring or shavings from the side of the block or something im not sure. but im pretty sure that it didnt come from the previous plug. also, i tried another plug and the same thing happened. and im pretty sure the threads arent ruined, there are just shavings in between them blocking them cuz its not like its stripped, its just hard to turn.

Chasing the threads while the heads are on will put even more shavings into the cylinder, right?

Do you have access to a boroscope? And if they are magnetic you got problems, aluminum isnt magnetic

You want anti-seize not dielectric
