I am slowly sticking my head into the 21st century . Does anyone have any advice on using these intakes to drill for injectors. I don’t want to change intakes. Thx b

what intake you have? I assume you must have work done to your current intake. Just need to account for the bung also and hope forcenough meat in the area you'll be drilling. Summit, jegs etc have special bits and even kits I believe Do a google search and some forums will pop up with some good threads. Good luck

I have some work into them, so I would prefer not to have to do it all over again , plus lose the bronze inserts that new manifolds won’t have. Thx b
