Get a good straight edge and some feeler gauges. Lay them across the surface of the head in all orientations. (across front/back/middle, diagnally across corner to corners) See if the feeler gauges will slip under at the end or the middle of the straight edge. (or you can see light...)
If so, it's warped. How warped is too much? If I can get my finger nail under it, it gets some attention.
Keep in mind that having it planed will make the surface flat, but bolt it up now and the camshafts are now continuously being bent ever so slightly...
Heads can now be heat straightened. This brings the cams back in too.
If it's not bad and you don't have a Torque to Yield head bolt setup, I've over torqued the head bolts by up to 10% to compensate on minor warpage. Seems to work. No leaks yet, although all car guys will probably say I'm on crack.
Most common seems to be heads warped away from the block in the middle. This is where I over torque the bolts just a tad in a reducing pattern out from the center. So, if the head called for 70 ft pounds I'd torque the middle bolts to about 78, next row out to 75, and so forth.
Don't blame me if it doesn't work for you or you snap off bolts.
answer answer
engine wont be warped but the head may be if you didn't overheat engine too much and fixed problem pretty quick, it wont be warped above answer says about bent cam. that is bogus but if head is warped, just go buy anew one and replace specially if aluminum they cannot be straightened if torque says 70 use 70.if u snap a bolt off going over the proper torque then you got to generally take head off and hope there is enough broken bolt showing to be able to remove it with out drills and easy outs PS a camshaft will break before it bends.

It could be either the head gasket or the water pump is sucking a little air. Most likely the head gasket though. There are chemical tests to determine if carbon monoxide is getting into the coolant. If it IS, you have a bad headgasket/warped head.

Why would a 1993 Plymouth sundance continue to overheat after having its thermostat replaced and its coolant refilled?
It could be a plugged radiator or a blown headgasket. Understand that many of the smaller, especially the Japanese engines are very fragile when it comes to overheating. If it overheated once you may have damaged the headgasket and warped the head. Don't forget the heater core either. If the engine warms up, but you don't get any heat, the core is blocked or plugged. Suggest you always replace the thermostat when you do coolant work. They're cheap and a quick fix.
Why is there engine oil in cooling system?

92 ford falcon you just changed the radiator and thermostat and filled with coolant as you broke down due to over heating now your car is blowing black smoke and the enging is shaking?
Overheated engines often cause the head to warp, resulting in a blown headgasket. If the engine blows out the coolant, you have a bad head gasket/warped head. If you're getting coolant in the oil, same thing. If one or two cylinders have very low compression, same thing. It's not news that anyone wants to hear, but I'd check that first since it's a very common condition after an engine overheats.

Would it be better to replace a head gasket or put in a recon engine on a y reg fiesta zetec?
Bit of a tricky one ... It all depends on the condition of the cylinder head. If the cylinder head is warped then replacing the head gasket won't solve your problem. A warped cylinder head can be skimmed (if not too badly warped). If the cylinder head is badly warped then it would be much easier to replace the head than fit another engine.

Is a '93 Mitsubishi Eclipse 1.8L with 130K miles worth buying if it needs a head gasket and has water in the oil?
If you get it cheap, yeah. Consider that there may be engine damage from blown headgasket. If the head is warped, you'll need a new one (couple hundred $$$) Headgasket and head stud kit will be another couple hundred for higher-end aftermarket performance parts. If you're shopping it out, labour is about $900 - $1200. i just bought a 94 1.8l eclipse with 127,000 miles on it and it took me about 3 days to fix it myself, luckily my head itself wasnt warped so all i had to do was replaces the gasket, that and the thermostat because often the thermostat brakes and you cant tell if the engine is over heating. I got mine for $250 so i got a pretty good deal, i say go for it as long as its cheap.
What to dew when you have slush in your engine after your cylinder head has crack?
If the head or block is cracked, it must be replaced. It's far easier to remove the engine from a Saturn when you're replacing the head. When water mixes with the oil, it emulsifies, and turns to a gel-like substance. After the head is replaced, change the oil; then drive the vehicle for a couple hundred miles and change the oil again. That should clear up the problem with the oil. But make certain that the head truly is cracked before you throw it away and get a new one. Usually it's not a cracked head, but instead it's typically a blown headgasket. A head can warp when an engine overheats, and when the head warps, the headgasket will blow. You'll need to have the head resurfaced if the head is warped.
What causes blown head gasketon 97 buick lesabre?
