Sory, I took things for the worse. You are still dealing with stubborn bolts, not the holes that have them in a firm grasp.

the strange thing is the driver side head bolts were easier to get loose. the passenger side every bolt has been fighting me. makes me think its been done before. it was the passenger side that was leaking.

also do you really have to replace both gaskets or just the one. i know it probly better to replace both im just currious.

You rounded the bolt head with a 6pt socket?

On mine, with a HG leak out the side near dip stick, that head was easy to get off. Other side was more stubborn. Machine shop said overheating will loosen bolts.

Would advise do both gaskets. And take heads for check and/or machining. One guy recently did a great HG job, had almost immediate leaks, found out that heads were .004 inch when he tore it down second time and took to the shop. For reference, printer paper is about .0038 inch. Flatness spec is .002 inch.

put a couple of the old head bolts back in the head to relieve some of the stress/pressure that you have on the rear two bolts.
I've gotten to the point were they are the first bolts I go after, I break them free then go back to the others.

see pictures of how I did it.
The shop before me pounded in the firewall.
So, that helped too.

got them out with a smaller socket. also helped to pound out the fire wall. the strang thing is the gasket didnt show any sings of it blowing and came right off. there is hardly any old gasket to clean up is this normal?

Find a shop you can trust, and they will usually have a hot tank that will make them look like new. Don't skip having them checked for flatness. Only a spec of 2/1000ths. That is half of the thickness of your printer paper. Shop will also do the valve seals with parts from your kit.

Here is a pix of mine before and after.

All it takes is a hairline crack.
Look for a crack the width of a hair.
it will be there.
Probably to the water jacket and cylinder 1,2 7 or 8.
