Who has ported a performer lower intake?

I'm doing a gasket match on a performer lower intake to a fel-pro 1250. I was looking at the injector holes inside the runners and was wondering if i could shave them down at all. They are kind of in the way and i'm not sure if i will hurt anything or not.

I ported my Performer lower to my 1250s & intake ports on the AFR 165s. I pretty much matched up everything but decided to leave the injector bosses alone and kinda worked around them much as I could.

It didn't turn out too bad either...

You can take them down (or up depending on point of reference) as long as you keep an eye on measuring how thin the runner walls get at critical points.

So your saying i can take some meat off of the injector bosses?

From the runner roof - yes
