DR, no head work. Athena, head cutting needed (squish band) or base spacer but that will not set your squish, will lower compression and slightly raise port timing. But, it would clear the piston.
Malossi and Polini I don't have personal experience with. I had a Polini kit for about a week but it had an issue and ate two sets of rings in mere miles. It DID need two base gaskets to clear the piston but I did not know at the time whether that was my engine or normal for that kit. I seem to have come across over the years that it is normal for the kit.
