Haven't decided. I would like to upgrade rockers b/c our factory rockers suck, but there would be no reason to use the current available rockers with our hydraulic roller cam.. If I was to switch to the adjustable rockers, I would switch to a custom solid roller. Doing that would depend on how often I would really have to adjust the valve train. I don't want to be adjusting rockers every few thousand miles.. If it's like the Cummins and I only have to adjust every 100k, I'd be ok with that.

 

I had a 496ci that had rollers and had to be adjusted about every 10-15k

 

Cummins has solid flat tappet and need adjusting like every 100k or something... Most of them go 200k+ before they actually get an adjustment though. lol
