We have not had any warping issues yet and we are just cutting the slots in the manifolds for added insurance. We honestly dont know if there will be any advantage/disadvantage to having them so some prefer the slots some dont. If you want them and didnt get them, just tell us and well compensate you for them some way or the other. Honeslty tho look how many different flanges dont have them and last a very very long time...

 

OK guys, just talked to a guy at max-rev and he assures me the bolt size is

3/8 x 24

 

You dont need washers or threadlocker, almost a yr. w/o either no problems, just fine the right bolt that works.

 

back from the dead...

has anyone used different bolts for these? i cant get any 3/8x24 to fit...
