Heads are not Corvette and have casting dates of October 19, 1972 (J192) and September 27, 1972 (I272).
Unless I miss my guess, the V1C23TJA is the assembly date for the engine. It's probably V1023TJA. What appears to be a backwards C is likely to be an incompletely stamped zero. V is the pant code for the Flint, Michigan engine assembly plant. 1023 would be the calendar date the engine was assembled, in this case October 23rd. TJA is the engine code suffix which identifies it as a truck block.
so.......what's the intake from????factory aluminum...thanks.....
