this might be a stupid question....but will a set of 1.7 rockers improve anything with an intake and throttle body? will they last on my e7s. i heard they are hard on valve guides?
The biggest downside is that you are spending 200 bones or there abouts for pedastal mount rockers when most aftermarket heads use stud mount rockers. So you are going to spend the money on the rockers, not notice any difference, start saving for new heads, and then have to buy new rockers for them, and then get $50 back on your pedastal mount rockers if your lucky when you sell them on ebay.
