hey whats up all.....ive got a few questions........i got a skunk 2 intake manifold for my 99 Ls.... and i have a new throttle body gasket and a brand new intake manifold gasket, the manifold gasket is not the normal "paper"one i guess i should say...its a flexable metal one...and i mean since i already would have the manifold off....im guessin i might as well replace it, right?.... one last thing...should i take it to a machine shop and have them check it to make sure its completly level where it bolts to the head..so that way i dont have any leaks?...and if i have to have it milled down to make it level...how much should it be milled down?
1. how long does it take to complete the swap on the parts..
2. is there any where or any site i can go to find out the correct way to do it
3. just out of curiosity...i know it wont be much to the wheels (maybe 5-10 if even that much)...but how much hp gain will i get out of it...
mods already done include:
*aem intake
* skunk 2 cat back exhaust
again ....thanks alot for any info that would help me out
