    what you want to spend on a set of 799/243 heads
    2002 Lightning - GT headed 5.5Litre w/ Twin 7665s
    2002 Silverado - 427Lsx w/ Twin gt4202s
    2010 Silverado crewcab Z71 - 5.3litre w/ procharger
    2000 Wrangler - 5.3litre with some stance
    2014 Xsport- 3.5 Eco boost
    412 Motorsports

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    I've got ported/polished/milled 862 heads on a 5.3 and I have to say that they did wonders vs. being in stock form. I couldn't say how much HP they added because I did a cam swap at the same time. They're currently going back on that same block just bored to a 5.7 this time around.

    $600ish for the port & polish on top of $250 for the millwork and spring install. The shop I used doesn't do port & polish very often, I only got it done because I was a regular customer.
