I got a 2.8l with a 2bbl. rochester varajet. It is runing very lean. I have mixture screws out all the way. Do jets and niddles from rochester dual jets and qjet the same as the one in my varajet. I really need to know because i'm putting headers on soon and I need to know if i can rejet. becauise the car in running lean enough with a high flow cat and a flowmaster, not so lean that it will do any harm but lean enough to roughen the idle. what can I do?????????
