Thread: Shaved head limit?

Tweet

I used to know but because of a diabetic memory,cheap beer,and TMB's, I forgot.What is the limit as far as cylinder head milling/shaving without having to shave the intake manifold also? And,,,even if I were to shave the intake,isn't there a limit before pushrod length and hydraulic lifter limitation would require changing/modifying? I would like to shave .010 off the heads.

When I first read the title I thought you were going Kojak!!

i have my storm vulcan book right here but .010 is no big deal. but how many times were they cut before? i cut alot of heads that is how i make a liven i do alot of small blocks and i take off .010 off the deck and heads all of the time with out any problems

Thanks guys.Pat,this is the first rebuild,heads have never been off.
29Street-rod,thanks to inherited genetic balding I'm about half way there But you just tell people,"God gave me one face,he liked it so well he's clearing off a place for another".
Let me ask this also,instead of starting a new thread.Is there a limit as far as how small of combustion chamber a 'race only' engine can use? I have never heard anything about this in my life.If I shave .010 off these heads I will have about 58cc chamber.My quench is .045,bore 3.905,4 relief flat top piston,CR would be around 10.33:1 like this.This may be fine,I don't know but if most motors perform best with a certain quench .035-.045 most of the time,then what of combustion chamber size,isn't there an optimum size or a limit?Couldn't you get it so small that you could create all kinds of commotion? I realize that dome pistons do this but they start with what,usually around a 64cc chamber?
