Default Spark plug gap

350 Chevy, 10.5:1, 292/501 cam, aluminum heads, HEI distributor.

What would you gap your plugs at?

I was told .045, they came out of the box at .035, the old set were at .040-.041. Someone today said they thought .035, but everything I have read says .045.

However, it was screaming with the .040 set, and runs like crap with the .045. I do not want to do this again more than once.

What say you?
