Holley 4160 vent screens

Will the Holley vent screens fit both primary and secondary sides or just the primary side?

Just the primary side. I like to use a vent whistle instead of the screen to help prevent fuel slosh out the vents.

I was just reading your tech page....and like that idea. How did you "stake it down" Wedge something under it?
Never rebuilt a carb before... Found the Vac secondary diaphram torn. Have to go to the speed shop tomorrow to pic up some parts and might as well get a wistle as well. Also, found #66 jets. Should I drop to 57s for a stock 302 with a cam?

I just bent bottom edge of the metering block up slightly so the whistle stayed in place. they actually fit pretty good without bending and usually once the bowl is reinstalled they wont come out due to them being longer than the space between the fuel bowl and metering block.
Hard to say on your jetting every engine is a little different but about all I could go down to was 60 or 62's I think i tried going down to 58's but it was to lean for mine.
