I pulled some numbers off my the block and heads on my car tonight and was wondering if someone could tell me what they mean. The only thing i know is the YE suffix code. They are as follows:

Front of the block right side:
03268 0785718
YE

Front of head:
03268

Side of Right head:
F059

Side of Left Head:
E299

I suspect the numbers on the heads might be month/date stampings but not sure. The car was built 5th week of August.
