So I got my head off
-How do you cover of the coolant passages when you scrape off the old HG or do you? I'm flushing the fluid out anyways so does it matter?

- I got a set of Topline rings for my stock pistons, but it didn't come with instructions. Should I just use the stock ring gap?

THanks

just try to scrape in the dirrection away from the holes. and with the rings, use the stock gap.

I'd recommend sending then head out to a machine shop. Have it hot tanked and decked, just in case, the block too. That would clean up a lot of the gasket resedue too.
