440 source ductile adjustable rocker arms.

I have a really nice set of Isky rockers complete with the hold downs and springs/shafts
ready to install.
But I need to get $450.00 for them.
The Isky rockers are the best Iron rockers every made but very hard to find in this condition
anymore!

I have had nothing but trouble with the 440 source rockers and the owner Brandon would not warrantee
then even though three grenaded in the first several minutes. I had purchase them several months
before I finished the engine and he said that was too long to warrantee anything. I like to have everything
in the shop before I assemble the engine for best use of my shop time. I had several adjusters break and even one come
completely out the top of the rockers. I had very light spring pressure and a mild hydraulic camshaft and we
have been building Mopars in our shop since we early 60's = the installation was done properly.

Also when I checked the remaining rockers after the failure, the ratios varied way more from rocker to rocker
than I had ever seen before..

Do try to find some Isky rockers from someone if you can find them, That would be my recommendation!
