I have had a mugello and a monza. The monza is fantastic and in my opinion a far better kit than a TS1. Why? i hear you ask, well,
1) you get a centre squish, very good quality head in the price.
2) The super monza piston is far better quality than an old asso one and most others out there.
3) more meat for further tuning
4) more or less same performance as TS1.
The Mugello is also an excellent piston port kit when done correctly. Still comes with the super monza piston (without holes! Lol!) and an excellent quality centre squish head. A certain shop sells them slightly reworked by one of the countries top tuners
No, i dont work for the shop but it's where i got mine from and it was reworked by that tuner and is now excellent.
For me Monza/TS1 performance is my kind of set up though.
