Thanks for the great reply - I guess I have a big decision to make. I just went out to look at the deck of the block and found the following letters in order from the radiator back; D A A E C C. So what the heck does that mean? I measured the sleeve openings and they are about 3& 9/16 across. The info about the oil and octane was very interesting. I had always used good oil but not low ash. I have been adding to the oil and the gas Marvell's Mystery Oil. I started doing this because I read that if I had soft valve seats they were not getting lubrication because of a absence of lead in the gasoline. It was recommended to add the MMO to help lubricate the valve seats. I double checked the bad valve and it does have a small chip broken off the corner about the size of a finger nail off of your index finger. I am saying this is the bad intake valve based on my presumption that the intake valve is smaller than the exhaust valve. I have made arrangements for the head to be taken to a machine shop to be fixed. Will the new valve seats that they order be hardened so as not to be affected by no lead fuel?
