    Who builds the best 23* head for drag racing?
    I have heard CFE makes a pretty goof raised runner head but I dont see it on their web site.
    All Pro are supposed to be top notch, any others worth a look at?

    All Pro hands down, .. .. no other comes close for the money, ..

    The CFE's are nice but 2x the price of a good CnC ported All pro.

    All pro will flow around 370cfm, ..

    I have a new cnc program I'm working up for a customer and have the
    all pro castings in stock, .. but they ain't cheap.

    Curtis,

    What can you do with a set of 23 deg AFR 227's I'm running on this 409 SB? Trying to decide if I want to put more money into them, buy a set of 15 deg or SB2's?

    Thanks, Bill

    Al,

    I'll drop you a PM, .. I don't do price quotes on the net, ..

    Bill, .. I don't think you want to spend much more on the AFR's if
    you're already thinking about 15* stuff, .. I wouldn't buy the used
    nascar sb2.2 stuff for a drag engine unless you plan on putting
    more money into them to get them right for a drag engine.

    I build a nice 18* head that is running faster then many nascar sb2
    engines in dragsters, ..

    what ever happened to the big deal with Edelbrock heads and people switching to them for 23* stuff ? I think they had some major builders helping them design a good setup.
    Yes All Pro, Niiiiiiiiceee stuff.
    pricy but you get what you pay for
