Reply to "Coolant or gasoline in oil?"

Okay, that is good news - compared to what it COULD have been.

Issue now is do you plan on doing anything to the heads, or just doing gaskets and putting it all back together?

If so, you should be aware of one problem area with the stock heads. The valves are two piece - that is, the heads were welded to the stems.

They are known to come apart. When they do, the damage can be such that it is new motor time.

Of course new valves, means at least a valve seat regrind. And while you are at it, the stock rubber stem seals are known for hardening over time, breaking, dropping little pieces into the oil pan, getting sucked up into the oil pump, and shearing the distributor gear drive pin.

With just 21K miles on the stock heads, they should have plenty of life left in them.. But new valves and better stem seals should be given strong consideration.

Your motor does look very clean with no sludge - a nice thing to see.
