Did not find a lot on here about this subject. I will be trying to replace the exhaust manifold gasket on my 86' 22re soon. Having done some mechanic work i know that the heating and cooling will cause the studs or bolts to become brittle, also the steel studs and bolts in the aluminum head ,if the break, will be a chore to remove. Right now im considering cutting or splitting the nuts off the studs to hopfully avoid breaking them, as for the bolts i dont know. If anyone has done this or has some good ideas i would sure appreciate the feedback. Thanks.
