Stan, my friend Leon is harder of hearing than you. What exactly did he hear? LOL!
And also, I think Panchitos are the absolute perfect head for a 2.0 liter or smaller. Probably still perfectly good for a 2110. And then we have Anand's motor making 200hp in 2332 size. So maybe I'm(we're?) wrong, and you should leave the heads be.
But you'll always be wondering what if? Perhaps order them regular, and if you don't like it, you can always rework the heads with 42s.
