Budget Rocker choice

I'm not certain there is one. I would think it all depends on which rocker and which particular head.

Yes, exactly that.

In other words, heads were cast like say body parts were made. One might measure one way while another another way. Same for rockers, so there's probably an infinite combination.

I can see that with the heads more so than the rockers but the amount would be small. It would still be a big issue when chasing perfect...
