Not that bad, they do cost horsepower. But my Mopar rockers are crap! I
have re-adjusted them 4 times already, Idid them last Wednesday, AND
THEY NEED TO BE DONE AGAIN! ARRGH!!!!
I think I'm gonna switch to Hughes rockers next. Did I mention that the
studs came unscrewed on two cylinders also. They suck, is my opinion! My
truck spends more time with the valve covers off than on. I have
adjusted them in several different ways and they always start ticking
after a few days. I have even had one of the adjusting nuts come off
once while driving down the road,
