Can I get an expert opinion please?

You used to be able to. I had to order a custom kit for my 420a back in the day piece by piece. If you know what size you need that is. Otherwise sell the z6 kit and buy the y8. I can advise against using a stock head bolt in its place. A buddy did that and it pulled threads in the block after heat cycles.
wtf happened to that z6 head?

New plan. There is a guy in Dallas selling as D16 w/ a Y7 head. That would be easier to bolt the Y8 head on to and I can have more power. The bottom end is beefier as well. I am going to try make a trip to get it.
