Hi,
I just bought my second set of aluminum heads in one month. This time I bought a set of NOS 3946074 HEADS. (PAID THROUGHT THE NOSE). My question is this, the boxes are original and I can't decode the part numbers on the boxes "3946072"???

Also the heads are dated 1973, I thought they only made the heads for L-88's and ZL-1's from 1969 to 1971? Any assistance is EXTREMELY appreciated.

Thanks,
Dan
