OK people. I just got headers for my 1975 fuel injected z. Well I took it to my mechanic and he told me not to put those headers on because it will mess up my air flow meeter. Is he right? or has he drank one to many beers. He said because I bought 6-2-1 headers, but i did not buy the smog fittings, it would cause problems for my car. Has any one out there have basicly a stock fuel injection set up but with MSA headers? Any problems?
