Crown of Super Monza vs TS1 pistons

Are the crowns of these two 70mm pistons the same. Just so that I can match up the new AF big cooling cylinder heads, when they arrive in the UK. I have a spare TS1 piston, but binned my super monza piston some time ago, so can't personally compare.
Now I asked AF Rayspeed the same question whilst on the Brid weekend, but they didn't know at that time.
Thanks
Paul
