VIN code "H" on '82 '83 birds

Hi, I'm new to this board. I have an "83 MSE Trans Am. The 8th digit of my VIN is "H", what is this supposed to be? The head numbers, intake manifold, exhaust, and carb all point to HO. What's the deal? Thanks, in advance.

I thought the LG4 engine did NOT come with the better exhaust manifolds, better heads, and the aluminum intake. Cause these are all the same as my old "84 L69 I used to have.

From: out of my mind; be back in 5 minutes....
Car: 1989 Firebird Formula
Engine: Internal Combustion
Transmission: Completed
Axle/Gears: ones that turn.
The heads are the exact same - the 416's were used on both LG4 and L69.

Camshaft, higher compression pistons and some carb mods are what made the HO (I think).
