Scorpion 1.7 roller rockers

Is anyone running these rockers? I am and wanted to know if anyone is seeing some significant vale train noise. Granted I am running these on Bart heads with a 228/232 111 LSA.

I am looking for some input from others as to how theirs sounds. I am also running a BBK all aluminum intake manifold, wich is probably also adding to the noise amplification.

The 1.7 with the TSP torquer V2 which is slightly bigger will add power and reduce noise slightly. Torque will improve more than the horsepower. I would imagine your BBK intake would insulate better than the stoke plastic intake.

I'm running the 1.7 scorpions with a 224/228 .600/.600 cam on 111 LSA. After the rocker arm install I didn't notice that much of difference in valvetrain noise over the stock rockers. In fact on the initial startup after install it sounded like my motor was coming apart. So I had a to clearance the underside of the valve covers a bit since they were slightly interfering with several of the rockers.
