A machine shop that rebuilds engines has equipment to regrind the valves and valve seats.
Reconditioned mobile phones are as good as a new mobile phone, as long as they've been certified by a technical expert from the company that manufactured the phone.
It is not good for the engine if it is the original setup from the 1970's. Lead is needed for lubrication to the valves. A reconditioned engine can use unleaded fuel if the intake and exhaust valves and the seats are replaced.
You can save quite buying reconditioned in some cases. Sellers of reconditioned goods often discount there wares to reflect the amount saved by not going through a third party retailer, which can often be substantial. Reconditioned hot tubs often include an original body with new pumps or filtration. Reconditioned hot tubs can give you a great "bang for your buck" as they often cost half what an equivalent new hot tub would cost.
Use whatever the original cap was, probably 15 psi.
Mini turbo engines can be found on many websites varying from brand new parts to reconditioned. You can also find information on how to build your own. Brand new turbo engines do seem to be hard to come by but you can buy most of the parts new but fully put together engines seem to be difficult to come by.

The main risks involved in using reconditioned equipment is the risk that the equipment was not properly reconditioned and therefore does not function properly. This may lead to longer times to complete a task or injury to the user.
Depends on the condition of the vehicle, but they can range from $3000 needing work to selling for well over $30,000 if the vehilcle has been either reconditioned or with original low mileage.
generally you could remove a head and measure the bore with a micrometer. then read specs on the vehicle and what it's original engines bore was. make sure an engine was not swapped into the original engines place.

I went on a hunt for a factory replacement radio/cd/cassette for my 1999 pathfinder. BY FAR, the best deals I found were on EBAY. Multiple options for new/used/reconditioned. I wound up with a reconditioned radio, excellent condition for a $150 (instead of about $450 for a new one). Good luck.
