Hi all,
I spent the day pulling off my carbs,rcker shafts,and old manifold in preparation for the mid-rise manifold that arrived this morning.
while cleaning up the gasket surface in the valley front and rear I noticed someone had taken a center-punch and made an indentation about every inch (somewhat random) along the top of the block at the valley gasket surface 12 or 13 at each end.
Also stamped at the corners is the letters FC and in another BF.
There is also about 10 or 15 little nicks apparently hand made around the perimeter of all the "valve keepers"
The block casting # is C5AE-H if that helps
Do these marks have any significance ???
Thanks , Karl
