Best plugs for street 340? Thanks for all the input!

I've run Autolite since 64 with no problems.I use 65's in my 440. I don't know the number for my small block and will change as I now use plugs for a magnum. The 5/8's heads makes tightening a pain. I raced with Maverick in the early 60's . The autolight guy help us find the right plug for the 13:1 max wedge and I 've used them ever since. Am I old? You bet I am!
