Hedman Elite Ceramic coating/ header fitment

[Sandtrap9072]

So i am thinking about buying a set of Hedman headers for my 72, but may need to massage them a little. have any of you blazer owners had any encounters with the coating on hedmans elite style headers. i have heard that you could heat them red hot and smack them without messing up the finish. Or do any of you guys know of a good header that will fit my 72 gmc jimmy with a 454 on sbc towers? Any help would be appreciated!


Thanks,

Nick
