I have a 99 tahoe with a 5.7/4L60e and 4wd are there any long tube headers that will guranteed fit or should i just go with shorty headers?

how hard would it be to make the egr work with tbi headers?Type “long tube header 4x4” into the search function there are a bunch of threads about long tubes that directly fit these trucks. Dont let people tell you they don’t fit. The headers that fit the TBI trucks work with a Vortec you just may have to do a EGR delete.
...and an EGR bung.If you run TBI long tubes on a vortec you'll need to add an 02 bung.
Long tubes never bolt up to the restrictive stock Y pipe. Any v8 needs long tube headers and dual 2.5” exhaustI've heard that they often don't bolt up to the stock pipes either, that they hang lower so you might have more work to do than you expect.
Or block off plate, which is what I did....and an EGR bung.
