Be sure you are running the correct plug gap. If this is ok then you have a fuel issue, you will need to have the vehicle tested as to why it is over fueling. Some reasons could be blocked air filter, excessive fuel pressure or low compression.

sorry i neglected to mention that only no 1 & no 6 plugs foul all the rest last as normal.

An air leak at the manifold or low compression on these cylinder will cause this. Also leaking valve stem seals.
