Default Exhaust manifold thread size

Does anyone the exhaust manifold cylinder head thread size? I am going to install four helicoils on the upper bolt holes since they were broken off. Am done messing around with the broken flush bolts. I am just going to drill them out and install some helicoils. Just trying to figure out what helicoil kit I will need.
