Greg, just wondering where the oil would leak to? If later heads the oil passages aren't there, right? Does it leak into the valley area?
I don't own any of these heads, but I'd assume the 07710 refers to the Julian calendar. In other words, the 77th day of 2010. That'd be March 18th 2010.
Aubrey, That actually makes alot more sense. I was trying to figure it out since it was only five digits, and the julian calender never occured to me. Thanks for the insight!! Either way, it appears these castings are long past the original flawed ones so they should be good. Gives me warm fuzzies.....:grin:
Never thought about that dating system either! But, I'm still good, but just by a few days! WHEW! This will make your hair turn gray! LOL Thanks for the input everyone.... Jim
