Lets see if I can get more opinions on this one. Anyone try these? good? bad? Just want opinion on the product it self.:violent1:
 
HS rockers are some of the best on the market. We run them on out Magnum Crate motored Dakota and have had no problems since we put them on 6 years ago.

Me too I have the 1.6 version on my stroker, so far so good I got them used off of Ebag.
I was missing some parts so I had to call HS and they were really helpfull, ordered the parts direct from them.
 
ya I will have to stick to 1.5 I think, the 1.6's make my wallet go on strike :protest:
 
That's all I ran when I was racing, good stuff. Hardend shafts are a must.
 
the HS that use roller bearing come with hardened shafts..........
 
I have heard that the use of roller rockers on a LA engine may create clearance problems with the valve covers. Any truth?
 
yeah... pretty much all of them in the instructions you are directed to dimple or cut the oil baffles in the valve cover to make room.

also i've been told by a machine shop that you are better off using the stock type valve covers rather than aftermarket aluminums, the steel valve covers tend to have less leak problems than the cast aluminum ones
