Spark plugs?

I did the Nutter bypass, hei distributor, Weber Carb upgrade on my 88 4.2 YJ a while back. It still just doesn't seem to run right. I still have to pop a fuel regulator in btw.
I'm assuming after these mods that I probably would no longer run the book recommended spark plugs for the stock set up. Any ideas of spark plugs I should be running now??
