davidssa, thank you for reporting back. We rarely get to find out whatever became of a problem. Out of curiosity, what were the readings in each cylinder?
If you do decide to do this repair, do some quick reading up on the basics of an internal combustion engine. The valves are in the cylinder head, so any valve problem pretty much means head work by necessity. But its also the case that you don’t really have to guess about whether the problem is in the head or the block (down where the pistons/rings are). A cylinder leakdown test can tell someone that.
Its also the case that for many cars remanufactured heads are available at very good good prices. Whether you decide to mess with the car or not, I don’t know. But if it needs head work you can often do better finding a remanned head supplier. (Your head would become a core exchange).
