Well, you could go with what Steve suggests. He probably has better knowledge and experience than I. But...The compression still seems on the low side for a recently done head. What is the mileage on the engine? Do you see any smoke from the exhaust at any time. Do the plug electrodes actually get fouled or is the insulator just getting spotted? Sometimes you will see weird types of plug fouling due to use of certain type of gasoline . How is the car accelerating? Do you see any evidence of blowby in the air cleaner housing? When you looked at the cylinder walls, were any of them scored, was there much of a ridge at the top of the cylinder?? BTW, when you checked the compression, did the tech assess the leakdown rate??
