Does anyone know anything about Yella Terra products as far as quality and dependability? Thinking about trying their L92 rocker arms. There aren't many aftermarket companies producing L92 rocker arms.:question:

The word on ls1tech.com is that the stock rocker assembly is just as good.. when you see side by side dyno comparisons the stock ones make marginaly more power on some engines.... if you want rollers the YT´s have a good reputation, but i would leave the stock hardware

I've heard nothing but good things about them. A lot of guys with the LSx use them.:thumbsup:
