    Milling the heads or even replacing the head gaskets with thinner ones also will increase the compression ratio and give a boost in power. The high flow air cleaner lets more air in to mix with the fuel for a better bang. The cam will change the valve timing to open the intake earlier and possibly higher and close the exhaust later for more cylinder fill and better power.

    All in all it's hard to tell whet the power is estimated at without all the specks but a safe estimate would be another 15+ or so HP over stock.

    Use a good brand of fuel in this motor and 93 octane.

    Milling heads is a good way to get some extra power, you can bump the compression back down if you need to by using thicker head gaskets should you find the ratio too high, use the best gas you can find to avoid spark knock:s
