Yea they have 2. one goes to 3/4 which is to small and the other goes to 1 1/16" and couldnt even get that fat dude in the hole

yea your probably right but i wanted to exhaust all my options before doing that cause if i go that far i am just going to go ahead and pull the motor and rebuild it but i just wasnt ready to do that yet.

You don't need to rebuild the motor just because you need to pull a head. It will give you a better idea if it really needs to be rebuilt though.

What is it that will tell me that? is it hard to pull the head with the motor in place?

Have you tried using a bolt extractor? These work amazing on rounded bolts and don't see why it wont work on the spark plug, just as long as you can get it in there.

Its like what 12 intake bolts, 5 valve cover bolts, 10 rocker bolts, and 10 head bolts plus miscelaneous. Come on man, in the time youve spent trying to shortcut you could already have pulled the head. Also, like 67t5 said, it will tell you how good of shape your engine is in. And no, theyre not that hard to pull in the car. I know a guy that can pull either head off any 60s or early 70s ford in an hour. I mean the average joe shouldnt take more thatn three or four hours.

plyers will not help anything if the sockert couldn't get it out. never seen a rounded plug. but i had in the past a few heads with plugs that wouldn't come out and the only way i got them out was with a pneumatic drill. it has the nice effect of hammering them out. if it's stuck like you say you might just break everything if you could get good grip.
so the first thing you need to organise is a socket that will fit tight (maybe different size, metric?) worst case hammer it on and then get it out with penetration oil and air gun

i would pull the exhaust manifold and put a pair of vise-grips on there

Are you using a six point socket?A six point should grab a rounded plug, but it sounds too far gone. I am wondering if the plug is cross threaded and if that's the case it would never come out.

If you do get something to finally grab it adequately get some help and a breaker bar or a length of pipe.
