IHs with 2ndry shorty injectors: More flow?
I had talked to a few people about 2ndry injector bosses......they mentioned that removed nearly the entire boss....on my siamese set I did the same and wow....plenty of meat for the injector.
So the next set I port....I leap before I look and do the same....and learned a hard lesson...however with error comes opportunity. There are shorty injectors out there and I have some on the way. So that means more flow in the secondary injector runner.....we will see if it means any more HP.

I believe there is also some room to simply shim-up the fuel rail mounting - as opposed to a "shorty injector" - similarly allowing you be more aggressive in porting the secondary

I can take down the lead up to the boss opening even more to smooth things out
