I purchased these BBC headers from Chris Clark recently. We both thought they were Appliance because they looked exactly like ones for sale here on the Yenko site.
But when I looked up the part number on my headers, they were different than the Appliance headers, which were CH22. Mine are stamped 5022.
chevyandpontiac (Dan) looked up my part number and mine are actually Blackjack headers...so apparently, one company made headers for multiple companies.
Just thought it was an interesting story.
Mine are out of the way until I decide if I’m going to use them or not.
Here is the ad for the Appliance Headers
