The only ones I have ever heard of actually giving you a gain was yella terra rockers. and it was like 6whp on a big cam/heads f-body.

I don't think they are worth the money unless they are your very last mod. and going to bigger ratio rockers like 1.8s or 1.85s you really have to start thinking about PTV clearances.

 

I used to have the Harland Sharp 1.7s. They clear the stock valve covers with out spacers.

I noticed some difference up top, but that was it.

 

are those blue stripe comps oh no!!!!!!!!!!!!

 

yeah from 2 years ago now. . . . . . replaced with recall springs !

 

I have the Harland Sharp 1.7's also...didn't notice anything from them, but they sure are purdy...makes me wish I had clear valve covers lol.

 

i would spend that money on something else

 

well eventually you start running out of things to add, besides a new motor...lol and all these little things start adding up HP quick then

 

like a bigger motor lol

 

yep there for that last little bit of power

 

well I guess I would have to go with 1.7's due to the tr224 I will be using
