Holly System Max 2
 
Has anyone tried the holly sysmax 2. I have it on my car and I have some tapping comming from my roller rockers, it gets louder the warmer the motor gets. I have heard the kits have had valve guide problems. Is this true ?


Any input would be great

What kind of rockers are you running? What valve cover are you using?

Bingo, this is why your valve train is so loud. These aftermarket valve covers don't hold the noise in so well, if your rockers are adjustable then it's possible they could be a little loose, most racers like to run them a little loose, but it's monstly just because of the valve covers. No worries mate.
