The busted spark plug still in the head? Get it out before buying a new head..!

You have the right idea to loosen stuck threads but at this point you need a way to apply a LOT more heat in a LOT faster manner !!

Take steps to protect the ECM computer from welding Google it before drawing an arc on your truck !!

One last resort is to use a stick welder 'n welding rod (1/8 ") with machine turned up high enuff to melt it not weld it ~ cut the rod length in half for better arc control ~ you can use heat tape to cover the areas you don't want touched with a HOT ARC ~ all the aluminum head area & around the spark plug's wrench flats 'n just arc in the center ~ try to maintain an arc long enuff to make the steel spark plug metal cherry red orange or even yellow ~ THEN COOL DOWN ALL THE METAL by giving the spark plug a garden hose shot of cold water, the colder the better ~ wrench only on COOL COLD METAL ~ wrenching it in both directions tighter & looser DO TIGHTER 1st ~ wrench on it like you're tapping threads with a tap ~ after you remove the spark plug you can use a 14mm thread restorer with anti seize compound to fix & restore the aluminum threads NO PROBLEM

ANOTHER METHOD: Chisle off the spark plug insulator & weld a hex head bolt onto the steel portion of the plug ~ taper the end of the bolt a little to help make a good strong bond ~ favor more taper in areas easiest to reach with the welding rod (use 3/32" size rod) shorten the welding rods for better control

ANOTHER METHOD: Remove the stuck spark plug by melting it out ~ I AM NOT SURE which is best for fire safety ?? Have that cylinder @ compression intake or exhaust stroke ?? I THINK COMPRESSION STROKE @ TDC WOULD BE MY CHOICE (that would present the least amount of cylinder 'n valve to possibly get crapped up)

ANOTHER METHOD: Done with cylinder head either ON or REMOVED from the engine ~ use a 1/4" die grinder with a bulb headed or end cutting cylinder shaped tungsten carbide BURR

LAST RESORT: Buy & install a new cylinder head ~ I think you can remove the stuck spark plug & hope you do

Stuck spark plugs might be caused by galled threads which can happen when dissimilar hard & soft metals are threaded together ~ I BEEN PREACHING NEVER INSTALL OR REMOVE SPARK PLUGS ON A WARM OR HOT ENGINE

NOTE: The 3M Heat Tape is pricey but needed ~ if the local welding supply stores don't have it then try government & military repair shops ~ you'll get it out even if you need to melt it out ~ everything after that is a piece of cake ~ any folks with decent stick welding skills can do it ~ good luck & have a way to extinguish any fires just in case
