SP Displacement / Rules

I have not been able to find Icssc's rules for Super Production. Anybody have an idea where to look? I know the rules are different from Oregon Region SCCA.

They are in section 1313 (page 62 of the 2020 Competition Regs).
SPO - over 4.0L
SPM - 2.0L - 4.0L
SPU - under 2.0L
Forced induction cars multiply displacement by 1.3 to determine class
