Casting numbers for 63 64 R2 heads?

[Guest]

Thanks for all the help guys!

I'm close to buying my first Stude, I'll let you know how it turns out but first I hear I need to check these casting numbers, anyone know what they should be?

Heads: 1557580. The block would have STAMPED into the left front corner on top RSXXXXX for Avanti Supercharged R2 Engine, JTSXXXX for Jet Thrust Avanti Supercharged R2 Engine in a Lark or Hawk.
