Got the head off my '50 8N and found what appears to be a very small leak into #3. Checked the block for flat and looks OK (less than .002 with the feeler gage and straight edge.
Head not OK, however - about 12 thou out of flat - low around #3 area - likely splains the problem. Took head to the shop & they will have it Monday - I don't know if a 12 thou shave will cause piston interference, but will check when I get it back - if so, die grinder is ready - way cheaper than a new head. I will not be able to get it back together until Thursday as I am tied up for the next 3 days, but hope to be back to mowing grass by Thursday afternoon - we'll see. Machine shop is familiar with 8N's, so I'll discuss with them when I pick it up regarding possible piston interference, plus they know not too take off more than they have to.
