    I tried searching, but the new search sucks. /forums/images/graemlins/doah.gif

    Which intake ports would a 81 454 out of a K30 be most likely to have, or is there an easy way to find out without pulling the intake?

    probably have the peanut port heads, pull a valve cover and get a head casting number, that should tell you. 99.999999% that will be oval port, just which oval port, the tiny peanut ports or the regular ovals.
