L31 Intake bolts

Quick Question:
What size or type of intake bolt does the L31 Heads use? I do know there not standard intake bolts.
Thanks,
Brian

Call Scoggin Dicky they should know. Or you should be able to get them at a Chevy dealer as well. I wish I could answer your qestion directly but I haven't gotten to that stage of my build up yet.

I used the 5/16 course thread bolt. It should be 1 1/2 inches long. You are using a vortec intake right? You can find these at any hardware store. No need to drive an hour for them. I bought 2 sets and the washers for 75 cents.
