3.0/3.2 upper cylinder air baffle on earlier engines

[Luke M]

I posted this over on the engine rebuild forum but figure it won't hurt to post it here too.

I had to remove my 2.7 alt housing and air shroud for some wiring updates.
My question is it beneficial to use the later 3.0/3.2 upper cylinder air baffle on earlier engines?

The tins in question are # 18

TIA,

Not sure, but there's a suggested sheet metal mod to the air deflectors highlighted in yellow (#s 14-16). Refer to any engine mod reference book (Bruce Anderson, Wayne Dempsey, etc.).
