have the mods in my sig, looking for more fuel (dont worry they wont go on till i get a turbo next month)... but what deliver valves should i get and does ANYONE make a GSK kit between 3k and 4k? 3.5k?! i dont want to float my heads with the 4ks but i think the cumminapart can handle more than 3k... any other suggestions for power that i missed guys?!
you may as well get the 4K and not install one of the springs to get the 3K and when you want the full 4K rpm you can install it. If you have an auto the 4k wont come into play if its set to shift at normal times anyways. the trans doesnt change its shift points just because your rpms can climb higher.
