    That is some nice motor work. How much more do the heads flow vs. stock? Did you try any mods to your stock heads? Like increasing openings, smoothing bores or anything like that?
    If that motor lets go that is just a reason to build it bigger and badder than it already is.

    ya they flow about 15-20 cfm bettter down low and about 12cfm below on top. on the prc 2.5 heads. they really woke it up it screams up top. i need a stall down low tho because of the power curve now.
