I-D my 440 heads

just bought a 67 dart gt with a stock engine the guy told me.It has a 440 not running when I bought it.He said it was a drag car when he bought but he never raced it.I have it running now so I pulled a valve cover to ID the heads and see it has adjustable rockers and I assume it has a solid lift cam.I got the numbers off the head but cant find a matching number from mopar.Here are the numbers 240651 and 12155 with this stamp DP
CD
can anyone help me...........
