Installation Notes

    These oval port heads will support over 540 hp with 9.5:1 compression when used as part of the Total Power Package®
    Unique oval intake port shape produces flow similar to rectangular ports, but the smaller port size provides excellent seat-of-the-pants performance and crisp throttle response
    Semi-open chamber design maximizes efficiency with streetable compression ratios
    Smaller-than-stock 11/32" valve stems promote excellent flow and lighter valve weight
