Help me diagnose why my head gasket blew

Well I want to update this thread. Finally got the engine back from the machine shop last weekend.

I posted in a previous post that the block wasn't machined correctly the first time and that is what caused the head gasket to go.

The Eddy heads were re-surfaced and the spring pressure were checked. The springs that came with the heads, the spring pressure were all over the place. So new springs were installed to match my cam. New seals, cause the Eddy ones aren't that great that come with the heads. Also a valve job was done.

MLS head gasket were used this time to get the compression where it needed to be.

We decided to re-use the block that I had. So I had to get new .030" over pistons. That were also cut to get the correct compression ratio.

Finally the intake had to be milled a little so that fit correctly.

I think that is pretty much it.

Now its just sittin in the garage cause its to cold to install it.
