White blue smoke?

[Jack's95gt]

I blew a head gasket about two months ago. I finished up the replacement today and started it up and ran it for about 30 minutes. It was fully warmed up and I had a white and blue smoke from each tailpipe.

What are the possibilities that there was more damage than the HG? Could it be the block?

if you didnt clean everything up then itll smoke for a little bit. assuming you did clean it up, you might of cracked the block. but do more troubleshooting before you jump to conclusions.
