Drilling Injector Bosses
Anyone know what size holes I need to drill for injector bosses? Is it a straight thru hole, or does it have features (counter bored, grooved)? I got this neat little GM intake with cast injector bosses that are not drilled out ... yet. I searched here and everywhere, but I can't find an answer. Thanks!

I believe it is 14 mm. I modded a victor jr for my 406 sbc and purschased a bit to bore my own holes. If I had it to do over I would have bored holes undersize and sanded out to correct size. O rings will seal better I believe.
