I believe the shop only removed a 0.002 - 0.003" when they decked the head. I assume the reason you would have to shim the rocker stands if they took too much off during the decking process, would be because you would not have any room left to back up the valve adjusters. Is this correct? The reason I'm asking this is that I might not have been the first one to have taken this head to the machine shop. More likely I'm the 2nd at least, since I know this is not the original head for my 261 (casting # tells me it's a 235 head). Thanks.
