Hey guys im planning on doing a head swap on my car. I have converted to mass air and im using stock injectors with the stock MAF meter. My question is if i was to swap in heads, and a 255lph fuel pump... Will there be an issue with fuel? Since i will still have the stock mass air meter, and 19/lb injectors? I would only run it like this for a month or 2, once i get more money to buy a bigger mass air meter and bigger injectors. Also when i did the head swap i would most likely install a cam and 1.7 roller rockers, dont know if that makes difference. So would i be able to run my stock injectors and maf meter, with those mods? What do you guys think? Is there a chance i could damage my motor somehow from it leaning out?? Thanks for your help guys.

you should be ok with the 19 pound injectors. be sure to check piston to valve clearance with the cam and rockers.

You will be fine with stock injectors. Definately spend the money to upgrade later though.

I'd have to say it depends on what head. A set of iron GT40 heads and AFR 165s are totally different.
