I have been PM'ing a fellow on the HAMB that just bought a stash of 30's Plymouth parts. He has not cataloged the inventory yet but the seller told him that the head in question is a factory aluminum high compression head. Research on ALL PAR shows this as an option for the early version of the 6 cylinder flathead (pre 35). He is wondering about the market for this head.
So do any of you fellows with 33/34's have any interest? If so I will get contact particulars together. He has yet to establish if the head is in good working condition. I do not know if he actually has hands on it yet, so it may be a while before it is officially available. I believe the CR is somewhere in the 6.5 to 1 area I think stock was 5.5 in 33 and 5.7 in 34.
