What did they look like? The 45s are a touch hotter than the 44s but either will work.

Looks like she was running rich.

Those don't look worn at all. Personally I'd clean em and gap em, then call em good.

You're running an HEI right?

The gap looks too small.

I'd back up what @bucket said and let 'em fly.
