the cam profile that i use will fit onto a 31mm bucket .my pistons are forged with a higher bump to give the 13.5 to 1 comp and uses longer rods as well ,i have both heads here as i dont use the std valves on any of these motors .only use the head with new valves and bigger plus different valve springs for the 13 mm of lift ,.head is ported and flowed and valve sizes are upped to the max

4 to into 2 into 1 is better for torque all round and reasonal hp 4into 1 is better for higher up in the rev range for hp but you loose low down torque at the end of the day the altezza is nearly 1.5 tonnes stick with the std system of 4/2 /1 or you will be reving the bee jesus out of your motor

You have said that you have changed the air box assembly ,there has been a lot of problems when you change from the std factory air box assembly to a after market 1 .As the air going over the hot wire maf changes and you will get a flat spot .Put it back to std and try it and see if that gets rid of it
