I know that it is best to leave full bowl flowing modifications to the pros but I would like to know if there are any minor areas or modifications that could be addressed myself that would improve things? I have been porting cylinder heads and intakes for 17 years and I am a self proclaimed master of the die grinder, so handling the tools isn't a problem. Can anyone give good accurate advice on the areas that should be reshaped/sharpened/material removed etc. etc.? I have both a Berkeley bowl and a Dominator bowl from the late eighties that are in stock form.
