Source for uprated H-1's being used on the C-2?

I thought I read that in Bilstein's Stages to Saturn but I can't find the reference so I'll withdraw the comment. The Saturn IB had uprated H-1s so it seems logical the the C-2 would also but of course that doesn't mean it was intended.

A 3-page article (attached) in the 14 December 1961 issue of Flight  (now Flight International) substantiates your claim.  A paragraph on Saturn at the end reads, in part:

    Saturn C-1. Stages: (1) eight 188,000lb Rocketdyne H-1 engines, (S-1 stage); (2) six 15,000lb P & W RL-10 engines (S-4 stage). Capable of placing 20,000lb in near-Earth orbit.
    Saturn C-2. Stages: (1) eight H-1 engines (S-1A stage); (2) four 200,000lb Rocketdyne J-2 engines (S-2 stage); (3) six RL-10 engines (S-4 stage). Capable of placing 45,000lb in near-Earth orbit; 15,000lb to escape velocity.
    Saturn C-3. Stages: (1) two 1.5m lb Rocketdyne F-1 engines (S-1B stage); (2) four J-2 engines (S-2 stage); (3) six RL-10 engines (S-4 stage). Capable of placing 80,000-100,000lb in near-Earth orbit; 30,000lb to escape velocity.
    Saturn C-4. Stages: (1) four F-1 engines; (2) four J-2 engines; (3) six RL-10 engines. Capable of placing 200,000lb in near-Earth orbit.
    Saturn C-5. Stages: (1) five F-1 engines; (2) four J-2 engines; (3) six RL-10 engines. Capable of placing 250,000-300,000b in near-Earth orbit.

Nova    Under study in several versions for possible direct lunar flight (with payload including propulsion system for return flight from Moon to Earth) as alternative to Saturn C-3 and/or C-4 using rendezvous techniques. Anticipated first flight 1966.
    All-liquid Nova. Stages: (1) eight 1.5m lb Rocketdyne F-1 engines (LN-1 stage); (2) two Rocketdyne F-1 engines (LN-2 stage); (3) four 200,000lb Rocketdyne J-2 engines (LN-3 stage); (4) six 15,000lb P & W RL-10 engines (LN-4 stage); (5) two P & W RL-10 engines.
    Solid/Liquid Nova. Stages: (1) solid-propellant stage; (2) solid-propellant stage; (3) four J-2 engines; (4) six RL-10 engines.
    The Nova vehicle would be capable of placing approximately 25 tons on the surface of the Moon, corresponding to an "escape capability" of approximately 50-75 tons.


EDIT:  Fixed several places where copying text from the original document had somehow transmuted '1' (numeral one) to 'I' (capital eye) or 'l' (lower case ell) to '1' (capital eye).  Expanded excerpt to include all Saturn and Nova variants.  Note that the Saturn C-5 described here differs in its upper stages from the configuration that was actually developed.
