I was looking at picking up a set of AFR heads and throwing them on and calling it a day or going gt40heads with gt40 intake. My question is can I just throw AFR heads on no problem? I'm talking stock cam, maybe putting on a gt40 intake but otherwise stock intake manifold. Part of this question is gains and benefits, I've always understood that a great set of heads on the 302 goes a long way and that the gt40 heads just leave you wanting for more. My desired gains on my FULLY STOCK 302 is 300+rwhp sooo would these heads achieve such desired goals? I believe I came across an article where they put a great set of AFR heads and mild other work and ended with 400+hp at the flywheel. A better statement for my goals is to say I want to break into low 13s preferably high 12s. Mods to follow this will be 4.10 gears (im in an auto), probably a custom grind cam from ed curtis (he's still active right?), and a proper intake or a cheap used powerdyne or votec supercharger to get that desired air flow and really use those heads (including injectors and fuel pump etc etc.). let me know your thoughts and opinions on my direction.
