Wow 1.8 Ratio Roller Rockers for 3.8

I just seen some 1.8 Ratio Rockers on SLP's web site has anyone tried this ratio?

wow , i would think that you would need a really mild cam to compensate for the added lift and duration that the 1.8 ratio would create.. with 1.6 ratio rockers you gain approx 2-4 degrees of duration due to the valve movement speed increase

1.8 is not too much of an increace,3.8's have 1.6 stock
