Long tube headers for 98 c1500 5.7 vortec

[Shawn2131]

So im looking at these headers https://www.jegs.com/i/JEGS/555/30066/10002/-1?_br_psugg_q=30066 does anybody know if they at least will fit and then will I just have to weld a o2 bung onto them for it to work. I really don't want to put shortys on if theirs anyway that I can make a set of long tubes work please let me know.

They are for a tbi truck. They should fit fine but if you are keeping egr you'll have to tap into them for that

They'll work. EGR block off and second 02 sensor bung and you're good to go. I used TBI long tubes on my vortec 454.
