Hello all, I tried stock (w/ dimples) valve covers on my 392 Hemi tonight. The guy who built the motor said it had adjustable rockers but it sure seemed like there was A LOT of room between the top of the rockers & the valve covers! I'm trying to get a pic posted. I wanted to check just to make sure that I had enough room even with the 'dimpled' valve covers. I only checked one side but I don' understand exactly what's up. Do the rockers stick up so far that you need the dimples or does the push rod end of the rocker hit w/out dimples? Oh, it has adjustable push rods. It doesn't seem to make since to have both adjustable rocker arms & adjustable push rods. What's up? What do I look for to see if they are the adjustable ones? Thanks! ; ) Bill
