I recently replaced the in/ex manifolds on the '70 C10 w/ 250 L6. It runs better and I have eliminated the pesky exhaust leaks that it previously had.

An ace mechanic friend of mine ran a compression test on the cylinders and found two adjacent ones running at low compression (25 and 40 psi, other 4 were right on at 130psi). He recommended replacing the head gasket as it is likely to be blown between the two low compression cylinders.

I would appreciate any tips and advice in replacing the head gasket. I have never replaced one and others have told me it will be "easy" to do. I'd just be more comfortable hearing from some of you experts before I dive in!

I have the gasket and am ready to go...Thanks.
