skimming head

[colourcraft]

Can anyone tell me how much should be skimmed off a standard head to work with a polini barrel and malosssi piston set up. and is that all that needs doing to it?

Cheers in advance

You will need it reprofiling to work with that set up best of sending it of to the experts
