im installing a set of prw ss full roller rockers on my vortec ho motor the roller rockers are the same size as the stock ones 1.52 3/8 self alighning do i have to change my push rods and do i have to get tall valve covers. im having dyno time in ct monday look at it.

some people say you can run the stock valve covers but I wasnt even close. I bought a set of hardin marine tall covers that are clearanced for the exhaust. They are very nice and sure save you alot of trouble in the long run.
BTW, mine is a BBC...
