Unless you really like doing stuff the hard way you should just sell that manifold and buy a new one from Indy that is already drilled and set up for fuel rails. If you insist on doing it the hard way I can sell you a kit of bungs and fuel rails that you can have installed on your existing manifold. You'll need to find someone who can TIG weld aluminum.
I'll have to go the hard way Andy, this manifold is for a B engine & 2 months ago, ICH told me they were out of stock & was unknown when they would have stock. Whats the price on your bung & rail set?, tig welding is easy as well as getting any machining done, thats what friends are for right?
