What I have been thinking is finding the head number for the 83 sec
That 84 500 Sec at $2000 Ebay didn't sell
Now I know the engine in that most likely would not compare to mine
Probably has different heads
Heads make a difference

I remember my TA had the 12 heads
D port
The Gto had different heads though same engine
Does that make sense
& the firebird
well it was a whole different duck
LOL


So what I am thinking is that I'd like to know what head my engine has


the valve covers in the 84 sort of look different

May not be all that important
but I get interested in the nitty gritty...
