When I rebuilt my 350, the exhaust valve rotators went back in. I'm not sorry, but am now wondering if I could have left them out and just shimmed the springs. The heads are "993"s without any seat work except grinding. I twisted it up pretty tight a while ago and may have floated a valve or two without any damage. (It had hydralics then, now it solids) We put about 8000 relatively easy miles on it a year and the performance is what I expected. I'm thinking I could get some more "Rs" out of it without the extra rotator weight, but don't want to tear (or burn) anything up. Should I keep them?? Thanks Kevin (Spring is coming soon!)

Having the rotaters out and the springs not shimmed for the distance taken up won't make any difference.

Top rotators or bottom rotators??

Bottom, buy rotator eliminators! Top, shim and use stock retainers... And maybe even -.050" locks to help lose some spring shim distance...

They're top rotatrors. I'm not as much worried about spring pressure because that would be an easy fix. I just don't want to burning anything up. Kevin

You will be fine!

I may yank em out. Were they used to prevent exhaust valves from burning up? Kevin
