spark plug gap?

So I have gotten the Starting circuit complete. she is cranking away. I'm putting new plugs, I wanna say that the gap is .045. any one know for sure

 

1985 chevy 350 Small Block

 

35 to 45 should be fine...

 

.035 for performance with or without electronic ignitions
Gas
alky
nitro
smog motors anywhere you want...cause it wont make any difference....

 

85 hei .045
