I have a 85 305tpi camaro I pulled off the fuel rail with the injectors my question is this. The very tip of the injectors has some sort of plastic piece with the needle in the middle a few of mine were cracked but the needle looked good The fuel rail was hard to pull off the intake and I think thats when it happened. Does this mean I need new injectors or just this little piece at the end. Or do I need it at all. thanks
The cracks could cause improper atomization of the fuel hence you won't get the best performance. If for some reason the do break off it could cause some problems with the intake valves or worse. I personaly would just replace them.

67 SS/RS restoring
You also could order a new set of high performance injectors from Summit. They have FP performance for around $450 or ACCELL for around $250. There compatable with your computer. I bought 24lb versus the original 19lb, which helps in future mods.
