99 Black/Black/Black C70 Conv, 109K, car is overall in good condition.

Hello all, so the C70 over heated and blew the head gasket :( I have confirmed with compression check, cyl 2, 3, 4 around 40lbs. So I am trying to figure what I want to do. I have a few questions.

I've done head gaskets on older cars and a few different honda's so I understand the size of job. How bad it is on the C70?

Anything special I should look out for or buy?

Do the heads normally need milling if they overheat? Should I do the values at the same time? It did have a tick before this.

I already needed to to do the timing belt so I will do that at the same time anything else I should think about doing?

Anyone have good instructions?

Thanks for any advice or help.
