MSD ignition 99tahoe...?

Don't plan on messing with the valvetrain until noises are heard lol. But I'll keep that in mind.

if you remove the cats performance will become an issue. if living in the country with terrain i would get shorties or mids to retain or improve torque output

btw rockers are easy really. if you did hear noise in the valvetrain in a vortec trust me you will have more then just valvetrain issues.

Which rocked are you recommending? I know they're not hard btw. Just didn't feel like messing with em, but I'll look into them if they will help with gains. Will they increase hp/tq output?

Rockers***

Do you also have a write up for the job?

1.52 are the simplest to put in with out modding the head pushrod holes and will give a slight increase 1.6 requires a pushrod hole *********** on the head. i use comp cams 1.52 magnum rollers right now. the vortec's use a 3/8" stud with self adjusting rockers and hardware. for more info read this and this.

predure to set them up is below.

Did you upgrade cam? If so, which would go best with upgraded rockers? While I'm at it, what else should be upgraded...? If I went with bigger rockers, I assume heads would have to come off and sent to machine shop for ***********, or could I do that myself?

Ok. I have the 6al, planned on getting the msd coil and wires when I did install, and eventually plan on getting a tuner and k&n induction, any suggestions on the tuner? If I ever have to do intake gaskets I plan on upgrading spider as well. How about throttle body spacer? Any other mods/upgrades that any of you suggest that will show gains in hp and mpg will be greatly appreciated. Thanks fellas.

I have a black bear tune and would recommend them

no cam upgrade and as i said before the 1.52 require no supporting mods.
