How can you tell if your engine is warped after blowing a headgasket and if it is worth repairing?

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.

When do you have to use a oversize headgasket?
After the cylinder head or block have been skimmed. For example. An engine has overheated and the cylinder head has been warped. The head is removed and milled so that the mating surface is flat again. The thickness of the oversized gasket will depend on the amount of material removed. If a thicker gasket wasn't used, the compression ratio may be raised or the pistons may come into contact with the valves
Changing head gasket on a 2006 grand prix?
The head, along with everything above it, will have to be removed. If the engine overheated then the head could be warped as well.
Your 96 cr 125 keeps blowing head gaskets?
When installing the cr 125 head gaskets, make sure to check the surfaces for any old gasket materials or scratches. Check the head to make sure that it isn't warped. Make sure that the cylinder pressure isn't too high. Tighten the head bolts in the proper sequence and at the proper torque, and the gasket should stop blowing.
1994 cougar V6 is overheating what could be causing it no leaks in radiator and has automatic fan?
Hopefully, it's the thermostat... but, if the engine has seriously overheated it could be a damaged head gasket caused by a warped head. Engine heads will warp slightly when the engine overheats, then there is insufficient pressure on the head gasket and the gasket will leak.
Why does your 289 Ford engine vibrate at 1700 rpm?
mine vibrated when the 'cotter key' wore down. the harmonic balancer was causing vibration at about 45-50mph. i guess i learned to ignore it and it warped my crank. --gussmolly@yahoo.com
What causes oil in your antifreeze?
rotted out headgasket and/or warped cylinder head . Aluminum head sensitive to no water in the engine.If it's just the headgasket it's not a big deal on a 4 cylinder datsun engine
How could water get into your oil on a 2000 dodge Neon?
Most likely causes are a failed headgasket or cracked/warped head.
1995 Mazda mx6 runs rough and pushes coolant out radiator cap can anyone help?
That's usually a sign of a warped head and bad headgasket, a cracked head or a cracked block. Those conditions usually only occur when the engine has been overheated.
How would antifreeze get into piston cylinders of 1997 Ford truck?
Either a warped head and blown headgasket or a cracked head. An intake gaslet will also blow and let it in on a 4.3. I had it happen.
Why does a car engine repeatedly need to bleed excess air from water or radiator?
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.
What effect will a cooling system failure have on a running engine?
Nothing good, I can tell you that. Anything from a warped head, cracked head, warped block, cracked block, and basicly, a blown engine.
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.
What happens if your engine overheats?
You can blow a head gasket or the head can crack or be warped.
How do you replace a warped engine head on a 96 Oldsmobile eighty eight?
First of all how do you know your head is warped cracked or no good lets start at the beginning
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.
My F150 knocks and blows white smoke but still has power what causes white smoke?
White smoke coming out of a vehicle means you need to either get your oil changed or the oil you have is too small of a weight. ---------------------------------------------------------------------------------------------- If your engine is warmed up and blowing white smoke , it sounds like engine coolant is getting into an engine cylinder from a bad head gasket , or a warped or cracked head
How does engine coolant get into the combustion chamber?
A bad head gasket , a warped head usually from overheating , would allow engine coolant into an engine cylinder
