They have too much info that comflicts if you read it more.

Also, why does every other Alum head company charge 2x what this company does? not just workers pay, possibly quality?

On the springs they come with what is good up for Hyd. flat tappets to cam lift of .550. You can always upgrade the springs for higher lift and I am sure thats what the information you read was all about. The .488/510 thing was something I posted.

For the money these are descent heads. Sure they are not AFR's but I just can't afford those right now either.

Should work fine on my application under I get the bug for more horsepower.
