Stripped out a drilled/taped hole in my sons alluminum transmission.
To fix it I got a Helicoil

With the helicoil, you will drill out the hole with their drill and tap it with their tap. Then insert the helicoil and install the bolt.

You should use a new gasket. When you torgue the head you partially crush the gasket. So pullling the head and using the old gasket sort of sets you up for a leak.

With my sons 65 mustang I had to pull the left head 3 times in one month. Gasket leak problem twice dropped valve once. Boy what a pain getting that straightened out.
