1mm head skim

[flipside]

what is the benefit of having 1mm skimmed of a k11 head?

obviously its going to increase the compression, but what about power.

will it have an effect the top speed,performance,torque and bhp ?

what about valve clearance is this an issue?

any advice would appreciated

it will raise the c/r to about 10.5:1 phil, will give a bit more grunt, and use a tad less fuel.
you will still have loads of p to v clearance

thanks for the speedy response frank . i've just got a price from an engineering shop near me, they want £60 for a 1mm skim.

thats quite expensive mate, 2mm is more worth while tbh, but it puts a lot of slack in the lower chain tho
