stay with 19s unless you are doing cam to go with those heads , not to mention a MAF ..... stockers should be more than enough AFPR is all you will need ......

19#ers are good up to 270hp or so there about, with an AFPR.

I heard stock injectors are good up to 350 flywheel horsepower.... but that is pushing it. So that is like 290-300 RWHP?

I wouldn't say the 19lbs will take it easy in the upper rpms but if you add an AFPR and bump it up a bit you will be fine...even in the "outrunning the injector" high-rpm phase...

Just to let you know the 93 Cobra has similar modifications done to it as your car has and it comes from the factory with 24lb injectors/matching bigger MAF...

You dont need them but when you decide you need replacements you could go one size bigger! If you have the stock cam I would sure like to see some 1.7 Cobra Rolling Rockers. Of course I am sure you know that new heads would make those bigger injectors really purr.

Well if you get the thumpers with the gt40 spring upgrade the 1.7's would be fine...that is what I had on my stock headed/springed heads so they would be fine with your stock cam with thumper heads/upgraded springs...

i would get the 24s and upgrade your MAF while your at it if you got the cash.

i would go with 1.7 rockers too with the stock cam and those heads. you will see more performance out of the cam and see what you want with those heads.
