Those rockers would improve performance because of the ratio change from what your current rockers are , CLAIMED 1.5 , to a claimed 1.6 , increase lift and duration without a cam change.
There is no real performance gain by just switching to a roller tipped rocker.
The quality of those rockers ???
Rockers arms are one place to not buy cheap Chinese junk . Ask those that bought off shore big block rockers because they were CHEAP , only to have them cause a dropped valve ...
Are U aware the PRW rockers are made in China... Most likely made from recycled Coors cans... The valve train is not a place to save $ buy the quality proven brands..
Just my $0.05...
Here's the one time I don't go on a tyrade on cheap chinese junk so I don't get banned AGAIN because I'm not a board sponsor sword swallower and I still get crap ...
YES those PRW rockers are cheap chinese junk , it appears the OP got that out of what I posted because he was surprised that I consider 400 some odd dollars CHEAP , seriously I thought the price was less , I just saw PRW and closed the link ...
That aside I also answered his question pertaining to a performance increase which a 1.6 ratio rocker would provide , granted it wouldn't be much .
