I received my rulebook yesterday and noticed under the cylinder head paragraph that it now states "any valve job permitted" without the 1/4" below valve seat cut being mentioned. Is this a typo error ? Does anybody have input on this. How about it Travis Miller,can you give us some guidance on this ?
