Re: Casting number lookup

From the heads i found this....

1987-’91 TRUCK, EXCEPT HEAVY DUTY AND ’87-’93 CARS: These heads were the same as the earlier ones except that they had three bolt holes on both ends. The intake surface above the ports was quite narrow; it’s only about 0.250" wide. The unmachined, cast ledge on the top edge of the head was 0.600" wide. Look for c/n 14094768, 10144103, 14099067 or 12553050. All of these heads had adjustable rockers.

14094768 Was the casting number on the heads which i'm sure was original

Also i think it is a T block for sure now, its stamped solid letters instead of the dots punched out making the letters.
