DON’T BE FOOLED!

Very nice. Now, what does he do to correct for rocker shaft location? I would suspect since that's kinda combination dependent, that's left to the end user?

Yes, he didn’t have my rocker gear when he set up my springs then I met him to get the heads from him.
I run standard Harland Sharp 1.5 stuff on mine.
The engine builder, said it wasn’t perfect, but close enough. No mods to anything.
Buddy of mine who Rod mentioned in the original post in this thread I don’t think has shimmed or moved anything either.
My heads have been on little more than two seasons now, zero valvetrain issues.
