I was cleaning up my intake manifold before a re-install and I noticed that the idle air bleed hole for #1 cylinder is a different diameter than the other 7 holes. Has anyone else seen this also? Maybe this contributed to split BLM's at idle.

Any help/clarification appreciated

Thanks
Steve

 

split blm's seem to be a common problem,as big cams and big heads,intakes and such, driveabilaty and tuning get complicated(they dont come from the factory this way for a reason)I too have split blm's as well as other issues though the car seems to run just fine,as for the intake issue,not sure if making them all the same size is going to do much,.
