What I have done for years is use a small carbide burr and convert the round shape of the steam hole to a tear drop shape. On the heads you need to elongate the hole upward towards the manifold. Then on the A-460 blocks you need to elongate the holes downward towards the lower head bolt. Then you need to use a Cometic head gasket from Lem with his own part numbers.

It was Fel-Pro that screwed everything up in the first place about 15+ years ago. Then any manufacturer who copied the Fel-Pro gasket blue prints continued to make the same error.

So what about a stock block?

A stock block has no steam holes.

What year did they go to the BBF2? I have 2 sets of BBF1's one set was purchased in early to mid 2008. The other set I have no idea as the so called serial numbers on the ends are different. A-1069-2 and A-1058-2 on the set purchased in 2008 and A-444A and A437A on the unknown heads. Both are 2.350/ 1.88
