Quick review; this set fit my 2014 Ram 5.7 perfectly. Bolts and nuts are well made.Now, here’s what I did because I have had this repair done before by a repair shop (didn’t work). First, don’t replace the exhaust manifold, have it surface ground. Mine was 0.050″ off port to port. Second, buy 8mm wave washers for the bolts and third, don’t torque the bolts to the full torque requirements. I went about 2/3rds full torque. Now, here’s my justification for these steps: the manifold is seasoned and shouldn’t warp more. A new one will have to “set in”. The wave washers will keep an even tension on the bolts at the reduced torque. Finally, with the washers you can use a lower torque that should help reduce the strain on the bolts. These are my recommendations and may or may not work for you. I’m going to see how well it works and will update as time goes by.
