What aftermarket injectors fit into a dohc zc with a factory intake manifold?

I bought precision 440's and they are too big.

 

Take a picture & post it... The nossle doesn't fit ?

 

they should fit dude, they are just REALLY tight, i used moly lube and the man hand to get them in

i put rc 750s in my dohc zc

 

There is stock vs dsm vs precision.

 

im guessing the one on the right is the stock 240cc?

if you are trying to put the middle one in i can see where you would have a problem, take out one of the insulators and see if it will even stretch around the base

 

It is in the order of stock, dsm, precision, the stock and dsm injectors both fit. The precision injectors are too wide at the base, the sprayer does not clear the intake manifold.
