    Default SBC Cyl heads Budget race

    Hi,
    Very much a budget racer changing my old Iron bowtie heads for Aluminum heads, Doing it more for the weight saving than HP.
    I am only around the 500hp what heads are good bang for buck??.
    What I have is
    Bowtie 184 Block 4.095 Bore
    3.48 callies crank
    6" Eagle rods
    Venolia Forged pistons
    13.12.1 comp
    Solid flat tappet
    4 stage dry sump
    Heads I want to change are phase 2 bowties with rollers etc and a Vic jr with 825 demon.
    It runs 7000rpm
    Whats the thoughts on intake runner size that would suit my application?, Would like to keep 64cc chambers.
    I have looked at AFR, Pro-filer etc, Would like any ideas.

    I think something in the 180-195cc range with the right cam, depending on where you want to make the most power. Upper rpm, use the 195's, lower rpm, use the 185's. I think the AFR 180 Eliminator head would make some real good power across the board, and the 195 Eliminator would make some real good upper end power. There's also the new Clay Smith Legend series hyd. roller cams for either of these combinations.
