Re: big block '72 k20 headers

I have been running and will always use either Doug Thorley Tri-Y or Stans Tri-Y's, they both have 3/8" thick flanges, are 14ga Steel and come either ceramic coated or nickel chromed.
I have had a set of Stan's on the 454 in my 68 GMC 4X4 for 26 years and its now finally getting time to replace them.
