Re: 906 Vortec Heads
If it has pressed-in seats, you'll definitely be able to see 'em. The early ones had a terrible valve job, it was practically a 90* angle into the port. The later ones are much better. All the 906's I've seen have pressed-in seats. Don't believe everything you read in the rags, either - most have retracted the statement about hurting flow. Once you've got the bowls cleaned up, short turns worked a bit and whatever chamber work you want, there won't be a nickel's difference between your 906's and the 062's.
