'05 Hemi ?'s

I had the same worries about the valves too. I keep the oil clean. After 7 years of hauling @$$ in it I’m not worried at all. Hopefully some builders here will chime in that have actually seen the problems first hand. Mine runs about 2300 rpm doing 95 down the highway. It has a rev limiter on it can be changed with tool. Factory I think is about 3800. I don’t see it going over 4500rpm.
