    OK first let me go back over why I'm doing this, I'm rebuilding a 305 for my 84 k5 because I've got a free rebuild kit (all high performance parts) and am picking up a 305 in a week and a half. I'm trying to improve over stock low end and midrange power while still keeping some kind of usable mileage. I don't need it to shred tires or anything. (In fact I hope it doesn't, they are expensive) I've got my top end narrowed down to vortech heads with a performer intake, or a set of torquer heads with a matched intake. Anyone have experience with either on a 305? It will be bored 30 over with a high energy 260 cam from Northern.

    That's the exact head I was looking at! That's about 60 bucks cheaper than Northern. What intake do you use? I wanted to stay away from the high rise ones that I've found for the vortech heads.

    OK, I asked the second question before I opened the second link.

    So, anyone else using torquer 58 cc heads for their 305? How do they do?

    I am unsure of the Chev aplications but in SBF circles the edelbrock heads have an unmatched rep for being 100% bolt on.
    most other aftermarket heads have small snags to the install apparently with Trick Flows having many quirks comparitively.
    third hand info that may be way outdated

    The Vortec's have alot more technology involved in them and out flow the torquer. Also the Vortec's still have small runners so shouldnt be hurt by your small displacment.

    All right, stupid question, but when Jegs says s/r torquer 305 heads $369 each, does that mean per set, or for each head. I know, stupid question.

    Well, who the hell buys one head at a time? /forums/images/graemlins/rolleyes.gif
    That's about what I figured they ran anyway. Thanks.

    Personally I think you should Get the World S/R torker 305 heads with 58 cc chambers. Or just take the heads you have into a machine shop and have them pocket/ ported and worked on.
    I dont think vortecs are a good choice for a 305. Vortecs have 67cc combustion chambers.
    Stock 305 heads have 58cc chambers. Using 67 cc heads will drop your compression ratio down to around 8:1= Lost power.
    If you use vortecs you will have to get the block milled to get the comp ratio back up. There may be valve clearance issues also

    Yeah, My other prob with the vortechs is the fact that most of the intakes for them I've found are high rise. Unless someone knows of a lower carb to vortech one. I'm looking more for torque than high end.
