how many hp....veli sensative question....but u will get improvement definately. plus if u drive wt lite foot u can have a better fuel comsumption by head skimming

dun worry...juz skim da head till da max n if yo engine overheat juz remove da thermostat n get a biger radiator

i skim mine.
performance is terrific.
need to get a professional to do it or else your valve will hit the piston head and become taugeh.
or else u can install high compression piston. it also gives u the power = skim head.

just my 2 cents only.

dun skim the head.
install wet NOS. NOS sure give u lots more power than skimming the head.
