Put the intake back on with 1 inch open spacers. Went and drove it after setting everything. Same thing. Above 28-3000 everything
its not a hard miss you can just tell it’s not happy. Gaskets are all good. I’ve replaced them every time I’ve had it apart just to be sure have sprayed and checked for leaks. The thing is it doesn’t do it with the single carb Weiand 8008 intake. I have ran it and swapped both carbs to it to eliminate a carb issure
