Yes. Their webmaster leaves a lot to be desired. If you call Ken, he will email you all of their current grinds lists.
And on the subject of pushrods, you may or may not need longer ones. It's all dependent on the build. The current slant 6 I have in Vixen running right now did not need them. I have tons of adjustment on the factory adjuster screws, but what helped me was the head has been milled over .150" so that helped negate the need for new pushrods. Don't just assume. Sometimes Ken can make a regrind where you will not need a pushrod change. Of course, if you're running original non adjustable rockers, longer pushrods will just about be a necessity. Either way, I would MEASURE, regardless.
