Re: 2.7 CIS engine questions

Howdy,
I am refreshing my 2.7 and have found some interesting things that I am not sure what to think about them.

First are the pistons, they seem to be higher compression as the raised area is larger than any pic I have seen.
These are stock CIS pistons

Second, I have discovered that the cylinders are Mahle and the piston skirts look like they are for the Nikasil type, but the inner lining of the cylinder has no magnetic properties Could these be one of the rarer Mahle Alusil sets?
I believe Mahle called this stuff Silimal (Alusil)

Third, the last person that assembled the engine pinched the head gasket (I'll attatch pics as soon as I get a good set) and subsequently dented the cylinder sealing face. Is this fixable typically?
2.7 heads are cheap, look for replacements

Fourth, there is material missing from two of the heads in the form of pits, can these be filled? the pits are about the size of BBs and there is one one one and two on the other.
Same as #3

If anyone knows what a ball park figure for some of these fixes are, or for replacements please let me know.
call, we'll talk

Thanks,
Mike
