Will valves hit pistons if too much is resurfaced off of head?

It's definitely possible in theory, but really depends on the specific parts involved, what their clearances were to begin with, and what the timing is. I suspect that by the time you mill that much off of a head, you may wish to consider that it may be unuseable for other reasons like maybe compromised strength or something.
Also worthy of note, in some applications, doubling up the head gasket is possible. People who do so usually do it to increase the engine dispacement by a small amount for whatever reason, but it could also serve to regain lost clearance due to overmilling.

What happens if a 1995 Honda Civic ex timing belts breaks?
Usually if the timing belt breaks you have to replace the head or the bent valves. Sometimes the damage can be much worse and the entire engine can be wiped out. When the timing belt breaks, your cams and valves stop moving but the pistons don't. The pistons will smash against the stopped valves and bent them and on some occasions can break pistons as well.
How much does it cost to fix car valves?
Need more info. It can be $5 for a Tire valves to $2000 from bent valves/damaged pistons.
How much to fix a head gasket on an infinity 2001?
Depends on if the head needs replacing or resurfaced. It will not be cheap for sure on an Infinity.
Is the cylinder head over the intake and exhaust valves and ports?
No. The valves and ports are in the head. Unless it's a flathead. Not used much in automobiles after 1954.
1979 Camaro how much do you think it will cost to replace blown head gaskets?
Depends if the heads are cracked or not. Typically $50+ for the gaskets (intake & head)... $200 if you ned the heads reconditioned... $60 if you need the heads resurfaced only... More if you need a replacement for a cracked head... Plus labor to R&R the intake & heads, readjust valves, add coolant, set timing, etc.
How much does the cylinder head weigh on a 3512 caterpillar engine?
120 lbs with Valves and Springs
Timing belt broke on 91 Honda accord?
It is almost a sure thing that you have internal engine damage. This engine is an interference engine and when the belt breaks the pistons will make contact with the valves. You will have to remove the head and find out how much damage was done. The cam belt should have been replaced every 90,000 miles.
What does 4 cylinder mean on car?
4 cylinder means that the engine has 4 pistons it means it has 4 pistons. the number of pistons can tell you how much speed and how much power
How much boost can the eagle talon handle?
Stock turbo can run close to 14 PSI...but you can increase as much as your turbo can. The engine will not last as long with higher boost. Upgrading internals such as pistons, rods, crankshaft, camshaft, and valves can allow much higher boost.
How much does repair for a timing belt on a 1994 Saab 900s cost?
You don't specify which engine, but since the 4-cylinder engines have a timing chain, we must assume it is on the V6. If you are replacing a worn belt, the cost is not too bad. Depends on the hourly rate at your local Saab shop. If, however, the belt has broken, you are likely looking at an engine overhaul as the valves will have hit the tops of the pistons. The result is bent valves and possible cracked pistons.
How do you replace the head gasket located on a 1988 Mazda 323?
Head gaskets don't usually fail unless there is a reason. Most likely the engine overheated or something else happened to cause the head to warp. If that is the case you will need to solve the REASON for the gasket failure.Pull the head then take it to a machine shop to have it resurfaced. They will make the head surface flat again and it can be re-installed without risk of it failing again immediately. While you have the head apart, you should have the valves and guides reconditioned. Once you have gone to all of that troule, you might as well rebuild the entire engine, since it isn't that much additional effort and expense to do the whole thing.
Does a warped rotor need replaced asap?
No you do not have to get new rotors just have them resurfaced. If they are to much warpage then you may need new ones. I would try getting them resurfaced before you replace them.
