Plug issue

[robcas47]

I was getting ready to swap out the plugs and wires for NG55's and MSD wires but when I pulled the first plug it was a TR6. It was still in good shape so my question is weather or not to leave them in for now and just throw on the wires. I bought the car with 42K on it and only put 10K on it, I checked the gap and they're set at about .55, I reconfirmed this with another plug on the drivers side. I know these plugs are supposed to be good for a while and the ones I just picked up are good for around 10K,(I think). Any thoughts on this, I know I'm being lazy about swapping the plugs.

Change them, since you already have the new ones, also who knows what condition the harder to get to plugs are in. Previous owner may have just left them being "lazy". Change them and forget about them for a while. Also they will tell a story about how your motor is running.
