Muscle Motors in LA, 818/341-7223, ask for Jack, tell him Mike from Madenterprise told you to call. Don't know if it will any difference but it won't hurt. I used to buy injectors by the hundred from him.
A few years back RPM outlet (I know I know..:shitstormretarded).had a sale on a complete set of 8 Accel 60# injectors for $299.00. I called Accel and talked to one of their techs and found out that Accel contracted with Siemens Deka for flow matched sets. Mine have worked flawlessly ever since...Give Accel a call and see if it's still the case and you can get a decent deal on a set of flow matched injectors if so. Just don't buy them from RPM outlet and you'll probably be in good shape. RPM outlet has a known history of shipping out the wrong stuff and then it practically takes an act of congress for them to get your shit right after the purchase.
