remove exhaust manifold bolts

I guess I got lucky. When I pulled mine, they all came out with ease, like they had just been put in the day before.
I guess your luck came over to me. lol.
Mine all came out super easy; too easy. That's why it was leaking coolant.
They didn't seem to be very tight. And the 2/4 port had a double gasket in there.
I've decided to "keep it simple" and only change the right side gasket. The driver's side is solid with no leaks. I ordered new hardware/studs and will be using them instead of the junk I took off.
