Headers for 5.7 Vortec Swap
Hi fellas, I searched but couldn't find an answer to my question. I'm replacing my 1987 LG4 with a carb'd 5.7 vortec. What headers will fit the vortec engine and also mate directly to the stock Y-pipe? I'm on a budget; trying to stay around $200-$300. I dont mind replacing the Y-pipe as well, I guess I just don't know what my options are. I appreciate the help!

Most good exhaust men can build you a y-pipe to fit your headers once you get them on or flowtech offers header/y-pipe combo though you may have to dent or beat on it a lil to make it fit. Check with Summit or Jegs.

there are no headers that will fit the stock y. All name brand headers should fit the vortec heads.
