What is the standard on the most compression

That's right and every single small block Chevy since 1955 has had quench ready heads. Every. Damn. One.
and you never hear any body in the chevy camp talk bout quench! and when thay do its bout exotic piston crowns and odd shaped dish's! as cheap as thay are to play with guess thay can afford the high octane fuel than can burn for it gose pop! lol
