92 Mustang, 302 , TFS TW heads, Harland Sharp roller rockers, Trick Flow stock height valve covers, Systemax intake. Vortech V1 at 10#s

I have -12 AN lines to go to a catch can. I need to put baffled fittings on my valve covers. My question is - has anyone used any of these,and which would be the easiest to use on my valve covers?

Moroso Vacuum Pump Fittings 22635
Or
Jeg's Vented AN breather fitting 555-52231
Or
The 12AN no weld baffled fittings on Ebay

Is there any one of these that is obviously better or worse than the others?

I have those and I get a lot of vapor through them - way too much. I definitely need a baffled fitting.

I just went ahead and ordered the Jegs fittings. It they don't work, I'll order the Star ones. The Moroso ones seem to be a little larger and space is limited.

I got the fittings today - they are huge.

Edit: Pulled my Trick Flow covers, checked the distance between the closest point of the rocker to the inside of the cover. It's just slightly too close for the fitting to go in there. Going to need taller covers to fit the baffled fitting in there.
Ideally, need another 3/8 inch to be comfortable, which means I probably need the spacer for the Systemax intake also.

I had a NPT plug in the systemax port. It was just a standard one from Home Depot.

I just pulled it to put a 3/8 fitting, as I am reworking my PCV system.

The new valve covers that I got don't work with my Vortech, so I'll end up selling them, and the 12an fittings. I'm looking for another solution. Probably will be to have some custom valve covers made with fittings.

The Jegs fittings look like they would work quite well and that price, it's hard to beat. Need the baffle, however. My local hot rod shop, Don's Hot Rod Shop in Tucson, AZ, makes a baffled breather with AN fitting, but they were pretty precious at $75/each.
