changing plugs
I found a nice 87 ford , only has 70k on it. started changin a few hoses,and doin some maint. on it,went 2 change the plugs(im sure they r origanal) and noticed corrosion so i sprayed them down with penetrating oil.now be4 i pull them out would it be better do do this with a warm engine or a cold engine.think i read somewhere that the 300 had aluminum heads so i figure i got 1 shot. man i would hate 2 pull the treads out. am i 2 parinoid or is there steps 2 take. plz any help would be greatly appreceated.

I've never heard of a stock 300 aluminum head, if you've got one then you've probably got the only one! To my knowledge there's only one & its for racing only (no water passages). Just pull the plugs out, don't think that you can hurt that motor.

just get yourself about a 4-6" extension and use whatever size plug socket (i think you need a 13/16") and run them in by hand till you can't get them any farther, and tighten them down with the rachet...that's how i've always done mine...and i've always done them cold, so i wouldn't burn my hands...really hate workin on a hot engine....lol...easy stuff to do...good luck...

YOU MUST DO THEM COLD! read any manual and it says this. even though no aluminum heads i use that silver thread stuff on the threads.

I had a 1989 with the 300 engine. while I changed the plugs at 30,000 miles the first time and around 60,000 miles the second time I still had difficulty gettting a couple of them out. I didn't use antisieze till I reinstalled new plugs at 60,000 miles. For removing the tough ones I was advised to work the spark plug wrench back and forth. It worked and loosened the plugs that would not budge by just trying to loosen them in the "normal" fashion. Spraying them with the penetrating oil will help also. And yes the head is cast iron. That engine is nearly indestructible.
