look like it'* time to do a little port and polish to the sc, tb, intake. Maybe even cook the heads and grind valves and seats.

the most expensive gaskets are the lowers, get the new gm aluminum for around $50. all the other gaskets a cheap.

not sure on head gasket price, I'm sure they will be quite abit more.

Based on club experience, this is most likely the lower intake gaskets and not a head gasket.

I would be inclined to tear off the intake and look for signs of a leak.

10x easier.

And I highly doubt it'* your head gaskets. I have yet to see a HG failure on this forum.

I'm assuming the car is not being driven at this point and even if it is for some reason, it'd be a really good idea to drain/replace your oil incase it'* contaminated by coolant!

It'* probably not head gaskets. Some suggested it could be a lower intake gasket failure, but the most common cause is an upper intake plenum failure. If it is an upper plenum failure, you will want to replace the lower manifold gaskets anyways because they are not too far behind and it'* a lot easier to do them durring an upper plenum replacement.

If this is what the problem turns out to be, make sure you update the lower manifold stove pipe by one of various ways.
