Looking for info on 340 Torker performance mods

For my torker, I just opened up the plenum a little and gasket matched to the heads. I also put on a 2.5" offy spacer with a 1/2" wood spacer on top of it to try and insulate the carb. (I live in the desert so **** gets hot)
Then I had my buddy sandblast it all to un-polish it to try and get some better atomization.
I left the runners alone in the intake to try and increase port velocity some too.
Not sure if all my mods worked; but it revved really snappy up to 7k, and it pulled hard up to ~6800.
