205 Block Eligibility

I have been discussing the eligibility of using the 205 block in a Pinto motor under the CAMS Tarmac Rally Tech Regs - Classic on another forum

(sorry).
I have not been able to get any hard info or facts as to whether I can use this block.
My argument is (and correct me where I am wrong) that the 205 block IS a Pinto block and is an evolution of it rather than a different block altogether. I am therefore not substituting but using the correct block.
CAMS' argument to me (via 2 emails) is that the 205 block is post 1982 and is not dimensionally the same as it is heavier. It is therefore not allowed.
I need to draw on your respective experiences as I am sure somebody is either running this block under these regs (I am told this is definitely happening in at least Targa West), is in a position of authority to officially comment, or can point me in the direction I need to go.
Basically help!!!!!!!!!
PS - please do not turn this into a thread about the pros and cons of the 205 vs standard block. I know that I do not NEED a 205 so just bear with me and overlook that bit
