The C9-B intake is a pretty common item. As the guys mentioned a 69 part. Cast iron either 2 or 4 bbl as it came both ways. The C9AE-8505-A is a 428 CJ waterpump and could be worth a few bucks to the resto numbers crowd. The heads you have given the date code.....there is a casting number like the other C9 #'s you posted. Could be C8, C6 etc...The 9A23 on the head is a 69/Jan/23rd date code. The 9BB is most likely a 9B8 not a B. 69/Feb/8th. Heads use a 6090 humber so look for Ex: C8AE-6090-H as an example. That will be located between the center two spark plugs. Dave is right on the stroke check. You can put on TDC and remove #1 and 4...that will give ya both TDC and BDC. Yank the head to measure the bore. You may or may not find a casting number on the block. The date code is below the oil filter adapter...same format as the heads date code....number/letter/number. 69 and later date codes have 2 dots under the first number. Block casting numbers were generic... and you'll find the same number on different bore blocks in some cases. So don't count on that to much.
