From my search of the forum/web I have found that:

20V ST = Non interference
20V BT = Interference due to ???????

Is it because of the different pistons OR the extra lift on the intake(?) cam OR ???

Can anyone confirm or correct the above?

yes BT is interference
i think its the pistons, can't actually remeber specifically

Pistons, no cut-outs for valves (can't remember, I think intake cut-outs are missign).

Dont think there are any cutouts on the BT pistons, Just a raised dome.

Bazda/Sergei are correct (Think it still has intake cut outs, but no exhaust cut outs). Would this cause the change?
