New coil-Spark plugs? 120-130

Changed my stock coil with a '85 240 coil. Just wondering if the spark plugs need to be changed with a different type?

Definitely! I'm planning on changing the plugs out because I have no history with the car. I thought since I changed the coil, I would make sure that it was OK to keep the stock spark plugs or not.

The spark plugs are chosen as the mechanical configuration of the engine dictates. (and the type of driving you do)

The coil affects primary ignition, not so much secondary. You can, however, open up the gap to get more complete burning that the old coil may not have been capable of doing.

The test of course if to pull the plugs after a drive and see how they look.

Nope, plugs should stay the same.
