Long tube headers on 5.7 vortec

[lifted2X4chevy]

I want to run these headers. Has anyone modified them to work with 5.7 vortec SFI? Are exhaust ports same on TBI as SFI?

All that would need to be added is a tube back up from collector to head for fitting to go in on drivers side.

Doesn't let me search from phone.

I had the Pacesetter long tubes for the 5.7l that were direct fit on my old 97 yukon GT that i had. Perfect fit. They werent the painted ones that were coated. Look for those if you want something that fits right.

For either of you, do you have 4WD? I'm having a hard time verifying that long tubes work on 4WD applications.

I know it says truck but it is still the same.

I don't see provision for EGR either.

Yes my yukon was 4x4. The firewall on the passenger side was the only thing that had to be modified. I had the egr tuned out so i didnt use it.
