So seem to have a lilttle bit of oil on my spark plug treads on the 3rd cylinder.  Im sure its not the rings because it did very well on the compression test, i got 178, 180, 181, 180.  So maybe its the little rubber seal that is around the valve stem?

That is a strong motor.  I had the same thing and it was that center gasket

Agreed, there is nothing wrong with those numbers.

It took more than 4 cranks though, is that bad? it took like 8 cranks and at 4, the pressure was only at about 150

It usually only takes about 6 cranks to get it there, but i still don't think there is a problem.
