Wow.. That's like $1100 in rocker arms dude! lol.. Definately cheaper than Jessel anyways and if you're doing a serious build I suppose it's worth it. $18 for lash adjusters is pretty reasonable I think, but I still wonder, is this really necessary? 700 whp.. maybe.. a 400-500 whp street car.. I think probably not. I guess only time will tell.

 

will a compression test inform of a bad adjuster, or do you have to take the valve cover off and look?

 

Take the valve cover off and look.
