### ⭐⭐⭐⭐⭐ 







  
  
    steam port
  

*by P***L on Reviewed in the United States on 7 September 2024*

Does not work on LS6 with a stock manifold keeping it for next engine that has is taller

### ⭐⭐⭐⭐⭐ 







  
  
    Pretty nice
  

*by B***O on Reviewed in Canada on 25 April 2024*

Fairly nice kit and hella cheaper than going with motion raceworks kit. If you do decide to get one of these make sure to get the proper seals (Dorman 56390) and also get a 1/4" compression to -4an fitting for the steam line. Also made sure to throw out the Allen head bolts and get some m6 x 1.00 30mm bolts to snug the fittings down to the heads. The Allen head bolts strip out way too easy

### ⭐⭐⭐⭐ 







  
  
    Didn't get all the pieces
  

*by B***I on Reviewed in the United States on 29 July 2024*

You need to take your time to figure out which part goes where to get it to look good as there was no directions or indication on what tube to use for what side.I was also missing a fitting to connect the middle tube.  I ended up getting a fitting locally and just running a longer rubber house.I can get around the missing directions.  When doing a swap, "making it work" is the name of the game, however, not having all of the pieces is a major set back.Quality of parts received was very good. Used tread sealant on the standard side of the fittings.  No sealant on the AN fittings which resulted in no leaks.
