I bought them from Mike @b3 around may 2019
At the same time I went to TF heads.
He was a Huge help after the first set of bushings wore out he warrantied them.
Then that set did the same thing he helped with sending RAU some extra needed rocker arms and shafts to make 1 good set.
He stepped up even when PRW didn't.
I really hope they made the necessary changes to make them a better product.
I can't say enough about how awesome Mike @b3 and Gary at RAU are!
Thanks guys!!
