Just did a forged build, got cp pistons, crowed rods, new valve guide seals, supertch bronze valve guides, and many other things. I'm only up to 300 miles on break-in, but its smoking blue on idle as if the valve seals were leaking. Is this normal?

Don't think so.

That's not good. You built it yourself then?

you 100% sure you punched those valve seals in correctly... sometimes its easy to punch them in at a angle installing them, they need to be straight on.
