Re: Head help....again

I briefly looked on line including Holley's website and apparently they don't offer those anymore. So I dug out an old 2005 Holley catalogue I have. It doesn't list any of those casting numbers as identification on the heads, but as fas as I know Holley only offered one set of small block heads. Here is the info it shows on them.
  • Valve Angle 20 degrees
    Intake Runner Volume 185cc
    Exhaust Runner Volume 68cc
    Combustion Chamber Volume 68cc

    CFM Flow @.500 lift measured @ 28" H2O
    Intake 223 cfm
    Exhaust 173cfm

    Intake valve Diameter 2.02"
    Exahust Valve Diameter 1.60"
    Spark Plug Angle Straight
    Deck Thickness .500"
    Exhaust Port location Stock
    Heat Crossover passage Yes
    Rocker Arm mounting Stud
    Rocker Stud diameter 3/8"
    Valve Guides Bronze
    Valve Spring Installed height 1.780"
    Max Valve Lift .600
    Valve Spring Force 132lbs
    Aluminum Head Weigt 30lbs

Re: Head help....again

if they are usable.. ie not warped beyond a decking etc... 350 is a good price for them.

We really cannot answer your question on What Its Worth.

It's a policy of the board that you have to be a paying member to ask that question or post anything for sale.

i believe that rule is if you're asking what it is worth and you're selling...



i can't see if asking if you're going to get ripped off against the rules.

Re: Head help....again

That cam will work fine with those heads. The real question is will it work with your short block and the intended useage of your truck. IIRC you have a stock 350 short block? Is that correct?
