Until the South American 45mm M1 kits appear on US shores someday, this thing is pretty much the best. What is not the best is M5 exhaust threads. I would suggest that before you install this kit, and invariably break your M5 studs/bolts, drill and tap those to M6. Some people like the more expensive Polini, but I honestly do not see the $100 performance gain between the two.
Edit: This kit is still the best. However, be sure to check out the spacing on this when you put it on. The base gasket is really thin and if you are not careful, the piston may hit the head when everything is torqued down after a few heat cycles.

If u get this kit you shall not be disappointed. Exhaust port and transfers are huge. Don't use a stock pipe cuz it chokes this kit, and bore out that stock intake to 15-16mm. Mmmmmmmmm.

Just a heads up that for simple slap on of this kit, you will need to have a post 85 morini engine. if it is pre 1985 you will need to have your case bored out about 2mm larger to accept this cylinder. Hope you get more of these in, this is a tremendous kit!
