I unfortunately was only left with a set of the adjustable rockers and a set of cheap aftermarket aluminum ones. The aluminum ones are 1.6 ratio and too much for this application.

Also pushrods would be rubbing heads that where already installed. It was put together by a shop here in niagara but very questionable
