You can run them, they will work, though it is not efficient due to the difference in injector spray angle piston bowl angle.
I had a similar situation to yours on my 91 innercooled 12v. Purchased a spare set of rebuilt injectors for cheap just to have and modify. They have sac style tips, 155*. I ran them for 2 days while I had my original injectors checked. They worked for what I needed.
I noticed the engine sounded completely different at idle and under a load. It ran smokey all the time, no matter the throttle position. All due to unmatched piston bowl and injector spray angle.
My plan is to buy different tips some day for my spare injectors. Tips that will match my piston bowl angle. You could do the same.
Read here. You will learn. (We need to figure out this photobucket thing for the sake of threads such as this one.)
