    pretty much the valves are staying open while the compression and ignition is going on.

    so best bet is a new head? i ono if you saw the psi's i pulled during the compression test but all but my 2nd cyl had readings of 80 psi and the 2nd cyl had 145psi so all but my 2nd cyl valves may be bent?

    The only way for fire to come out of the intake is this ^ or the ignition timing is effed as far as I know.
