    31110 - FlowTech Headers is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from 1966 Nova 2 I purchased the 31110 flowtech headers for my 350 V8 Nova 2. The install went pretty smooth. The right side I had to remove the starter and lift the motor a 1/2 inch. And the left side I removed the oil filter and clutch rods. The only problem is the alternator bracket is to thick and I had to grind it down a bit. Not that big of a deal. Otherwise I had them on in a half a day.
