come on man.. is that response needed??? you answer my question by saying my 148 may have a different runner. just that would have been fine. cobalt327 answer by agreeing my compression would go up after saying theres different variable effecting compression . then i ask if the difference between my 148 and the 049 is the runner volume/design assuming the valve size is the same and the cc volume and all other variables between the two heads. that shouldnt be a broad assumption.
