headman header ?

[shmed]

ok i have a set of the gs club headers on the mygn with the remflex gaskets.
the other day while showing off,,,, i blew out the gasket.
so today i pulled the header off an laid a straight edge along the 3 header tubes an none of them are in the same spot. my question is is there a tolerance that the header will pull ?
or should i take them to a machine shop?
thanks

Had the same issue with mine, take the time to get the surfaces trued.

Yep save yourself the headaches and have them professionally machined. Check for cracks first. Money well spent. Had my DS done over 5years ago and never an issue since, and flange to head NO gasket.
