Suggestions on which plugs to go with

Why's that? Do they foul easily, have poor life? What do you suggest for 11:1 compression?
I was being facetious. You will find spark plug threads will usually have someone trashing every brand of plug by the end of it.

I like NGK and Champion plugs in my junk. I’ve been running Champion N9YC in my Commando 273 which is 10.5:1 and they were a big improvement over the autolite that came out(same heat range).

Whichever plug you choose, carefully inspect each plug, and verify the gap before you install it.
