Can anyone here please give me the part number for the racket piece I have an arrow pointing to?

 

the cam cap? there is no part number since you can't buy it separately from a complete head.

 

Well that isn't good news :/

 

You can still get cam caps from a donor motor or a junkyard.... You just have to make sure to LINE HONE it. It is possible to get away without line honing it but it is not recommended.

What I mean by this, is that each cam cap, and each cylinder head are created uniquely....

What is the problem? Did you break one of the bolts or something for the distributor? You might not need to replace it.
