Plugs fouling, left side only

Thinking of going to hotter plugs, presently autolite AR 3924.
Any thoughts/input appreciated.

smell the plugs.....will tell you oil or gas fouled.

hell taste em' if you have to...
if oil then its the gasket, if fuel its the sync.

whats that old joke?
smell it, feel it, taste it.....ok now we know not to step in it....

Don't mask the problem 24s are hot enough this is a one side issue. Usually oil has a little shine on the plug at end of the threads on the rim. Gas is dull and rubs off easier. Did you check for head intake alignment. How was the previous gasket leaking. Rule out oil first that's the bigger problem
