Big Block Adjustable Rockers

Hi all

I need a set of rockers for my 471 Big Block with ported 452 heads. I was running stock till they bent... at least previous owner of the car saved some cash ;-)

Would be great to get a set with pushrods if no cup style valve lash adjusters are in.
I have hydruaulic 507/510 cam. Was thinking to go with 1.6 ratio perhaps?
I think oldschool Crane would do good, but perhaps roller are that better and this ratio change will be a good idea?

Please PM me with offers!

Thanks!
