Brad, I think so, but you know my memory isn't what it once was.

dbradley: Yep, I even backed off the rockers all the way and it made no difference. These are brand new 305 Vortec heads, so the chances of something there being wrong are probably slim. When I looked at them today all the valves seem seated well.

sg4356, I kinda thought so too. I was able to take my fingers and rock the piston a little in the cylinder. Not a lot, but noticeable. In the next couple of days I am going to get that one out of it's hole and should know more then.
