Does any one have a picture of the aluminum tag found on some of the 51 308 heads? I had one but can't find it and want to make a new one to go back on the head. I believe these said "High test only" or something to that effect. They were used during the aluminum shortage. I had a picture posted but can't find the old posting on the forum.
Thanks!

    HUDSON HEADS
    The July, 1951 Hudson Service Merchandiser notes the following about 1951 heads: "Beginning with the 1st
    production, an aluminum head of 7.2:1 compression ratio was standard. The marking on top of cylinder head
    was H-145 Super Power Dome-304632 (this is casting number). The optional cylinder head was of cast iron,
    6.7:1 ratio, with marking H-145 Power Dome-304630.
    Later, a cast iron cylinder head, 7.2: ratio, was used as standard-marking H-145 Super Power Dome-305923,
    and a metal tag with the imprint USE PREMIUM FUEL. The present and final change for standard head 7.2:
    ratio is of a new casting with marking H-145 Super Power Dome Use Premium Fuel-305854."
    The metal tag head was simply standard equipment.

    Puzzles me that both compression ratios had "H145" on them.  One would think that the higher ratio would be higher horspower.
