How to tell injectors apart?

How to tell injectors apart?
I bought some injectors a couple months ago used. They are supposed to be F1 Mach 7's. Im just now to the point of putting my motor back together and when Im going to install the injectors I compared them to the old ones and the part numbers on them are the same. Does F1 just use a stock housing or what? How do I know if these are truly what they are supposed to be? The nozzle itself looks slightly different but it is such a small difference it is hard to think that could make 240hp difference. Please anyone that knows let me know. Thanks.

Clean the injector nozzle tips and count the holes in each. The holes are very small, you might need a magnifying glass. I'm not sure if they use the stock bodies, a lot of them do. Sorry I'm not more help.

This is a great question I just got some 370 for my 12 valve and as I was installing them I noticed the numbers on the body were the same and I thought the same thing.

Maybe the numbers are the same usually. I know DDP wants my stock cores back, so maybe they just use the bodies and change out the needle valves, spray pattern, tips, etc.

You have to flow test them and see how they spray out the end of the nozzle. Don's is abit different on the spray angle, than dodge or the jammers. You have to send them to Don. Have him clean them and flow test them. If anything is wrong, Don would fix them properely. I would stamp/mark the top of the nozzle body to make sure you get you're back.
