I have searched all over this board and have read that ford injectors are supposed to be good. However, I don't want to get 24# injectors because all I have on my 91 TPI 350 are headers, exhaust, AFPR, gutted air box and TPIS air filters. I would like to get 22# injectors, because some of mine are starting to go, but there doesn't seem to be many choices. I found these two types which are reasonably priced and was wondering which would be the better choice.
I know to stick with stock size injectors, I thought they were 22# for the 350 is that right. I am just wondering which of these two does anyone have experience with and which is "better". I was thinking about going with ford 24# and having a custom chip burnt by fastchip, but would rather wait until I do some more mods (cylinder heads, cam, intake, runners).
Be careful with Ford and GM flow ratings. They rate them differently. Ford 22# injectors actually flow more than GM 22# injectors which might be why you've heard that Ford injectors are "better". Get GM 22# injectors for your setup. Smaller injectors and higher pressure equals better fuel atomization and more efficient burning. For all intensive purposes you have a stock motor and have no need for extra fuel.

After re-reading the post if you can afford any down time on your car just pull your injectors, send them to get flow matched, and re-install them with new O-rings. That should cover your problems.
