I recently installed new spark plugs in my car and they fouled out rightaway. I have dart iron eagle heads and i put the recomended plugs in witch are accel 262 plugs. this is one of their colder plugs. im not sure if they are to cold due to the build up of my motor or what. Im running 10.5 to 1 compresion, comp cam at 230 230 with rocker arms at 1.6 ratio. 600 cfm carb and a performer rpm intake.

Any help
