Clearcoat on engine

I've read lots about the clearcoat yellowing on an intake manifold. Most I've read is when using it on an intake. Also those intakes always appear either "raw" or painted aluminum. My question, is how does/would it work on the engine when painted oem colors? In my case red. Would the yellowing be noticeable with a red base? Discoloring the heads/block?
I'm finishing up my sb build and I've already put some chips in it just sitting on the stand lol. I used MP oem red paint over top of Duplicolor engine primer.
Thanks
Steve

Looks fine to me Steve. I used the same paint you did and I primed before final coat. Left the primer for two days with garage at about 70 degrees.

No clear.

Duplicolor Hi -Temp red.

Light coats.

Came out great!
