My 383 Stroker required different lengths due to some of the brackets bolted on to the front of the headers so I got this longer length kit and cut off the lengths needing to be shorter. This is my second set. I got tired of bolts coming loose now and then and frying my gaskets as a result. You have to have patience with the small plate that mounts over the bolt head. They may not fit perfectly flat due to the orientation once tightened. I typically just grind them a little to make them fit. No more loose header bolts! I've had my first set for over 4 years and no issues in all that time :)

Prompt Delivery ,Prompt packaging . Great Product , Works as designed to keep from unlocking When they are hot or cold ...The only problem they should make the Hex Head with the allen wrench opening in the center of the bolt because you cannot torque the bolt ! ! !
