heres my combo , i need more.....help

Keep everything as is and buy a set of Magnum or Magnum RPM heads for it. They flow better and will raise compression. You can get them with LA intake bolt pattern.

Check Hughes Engines for them.

My next swap would be to a small solid cam. Something in the 230 intake, 240 exhaust duration @.050"

The M1 wouldnt be my first choice but with your gears and converter you'll be ok.
