head gaskets for aluminum heads

A few years ago, i picked up a 1978 chevy one ton 4x4 dump truck. A few weeks ago, while hauling firewood, the motor started to heat up. After waiting about a half hour, i added a gallon of water and drove six miles home. On the way, it started blowing anti-freeze out the exhaust. Fearing i cracked or warped a head, i started to tear it down last night. The head bolts weren't real tight (3/8 ratchet, little effort). The head gasket looked like hell. I put a straight edge on it and there was about a 5-7 thousanths dip between #3 and #5. Is that too much? Can I just replace the head gasket. It is a small block motor with aluminum heads, casting #10088113. Block is a '78 truck block. What gasket should i use, and what else should i do? I need to get it back on the road. Thanks

I would resurface the heads and make sure you use a head gasket for a aluminum head engine.

You can save the heads by having them milled. But I would replace them with cast iron ones on a working engine.

Why would anyone put alum. heads on a truck engine?

Sell them, they should bring enough to buy a new shortblock.

What size engine is it?

Thanks for the reply. Cast iron heads on the way. What are the aluminum heads worth? 58 cc angle plyg, raised D port exhaust 194-1.5 valves.

If they are the 113 castings they should bring about 250 to 300 for the pair at least in the philly area they do.

I gave $1,000.00 for mine (bare heads) used at a swap meet at Bristol Tenn. Mine have the raised intake runners and a lot bigger valves.

If anyone has a set for $200--$300 pm me, please.
