not sure what you're referring to as a "compression ratio tool". There isn't any device (that I know of) that would take into consideration all of the variables (cam lift, durration, etc) that would allow a plug and play type setup..
please explain..
i'm with you on this one, i'm pretty lost as to what he's even asking...
just tell us the combo and i'm sure someone can tell you what you want to know. you said something about head gasket thickness. are you going up or down? as that all your trying to find out?
