    Looking at getting another set of aluminum heads for my motor.Looking at the AFR's now, but don't know which are better for my needs.Motor is:
    350 bored .030 over
    Flat top pistons
    Voodoo 103 camshaft
    High Performance street cam likes 2400 RPM stall, 700 cfm carb, dual plane intake and headers. Makes un-equaled power to 6200 RPM with proper valve springs. If you're looking for a Very Strong cam with great street manners then this cam is it.

    Advertised Duration (Int/Exh): 268/276
    Duration @ .050 (Int/Exh): 227/233
    Gross Valve Lift (Int/Exh): .489/.504
    LSA/ICL: 110/106
    Valve Lash (Int/Exh): Hyd/Hyd
    RPM Range: 1800-6200

    Holley 300-36 dual plane intake
    Jegs headers
    3:42 posi Turbo 350 with 2700 stall converter
    Holley 770 street avenger carb

    Which head would fit my motor needs better?And what cc's would you use.I was looking at the 65cc for optimum quench.Give me you input.

    180s for your 350. 195s for a 383, 210s for a 406-408

    I am running that same cam in a 406 with AFR 195 heads with 65cc chambers. My block has been decked and with dished pistons my compression is 10.7:1 static. The engine pulls hard, is fun to drive and gets decent gas mileage.

    The 195 Eliminators were designed to be run on the 2 most popular SBC engines- 355/383.

    You don't need 195s on a 350 when they'll feed a 400 to 525 HP and 6500 RPM on a HR 236/242-110 cam. You're not spinning your 350 fast enough to benefit from huge 195s.

    My 350 .060" over with approx. 9.7 compression has the AFR 195 65cc Street Eliminators. (Need to change gasket to improve quench thou.) B/W ST-10. Sorry no time slips but I did have to get a rev limiter too keep it under control. The parts I selected were for up to 6500 rpm. I wouldn't recommend this cam for an automatic it only gets 8" to 9" vacuum at idle.

    Cam Specs Hyd.
    int. 240* ex 246* @.050"
    int. .507 ex. .510 total lift
    LSA 110

    RPM AIR GAP
    Holley 750 HP
    670 Street Avenger works too

    AFR 195s have a solid rep.

    Spoke with him before ordering mine.

    Rene what is your quench? I have mine at .049". Had to deck the block to get it there, no one makes a thin gasket for a 400 sb.

    Yeah I messed up here, lack of knowledge at the time. Afr has a gasket that matches the Felpro 1094 and my supplier couldn't get the AFR gasket so they sold me the Felpro 1034. I need the .015" thick gasket to get that optimal quench. I'm sitting at .066 or something stupid like that. .025+.041"=.066:mad:
